Category "Cc" control codes can serve a variety of purposes, not limited to format effectors: for example, the default ASCII C0 set includes six format effectors (BS, HT, LF, VT, FF and CR), ten transmission controls, four device controls, four information separators and eight other control codes.[4] Most of these characters play no explicit role in Unicode text handling, and are used only by higher-level protocols such as those used by terminal emulators. Certain characters are commonly used for formatting or sentinel purposes:
There were quite a few control characters defined (33 in ASCII, and the ECMA-48 standard adds 32 more). This was because early terminals had very primitive mechanical or electrical controls that made any kind of state-remembering API quite expensive to implement, thus a different code for each and every function looked like a requirement. It quickly became possible and inexpensive to interpret sequences of codes to perform a function, and device makers found a way to send hundreds of device instructions. Specifically, they used ASCII code 2710 (escape), followed by a series of characters called a "control sequence" or "escape sequence". The mechanism was invented by Bob Bemer, the father of ASCII. For example, the sequence of code 2710, followed by the printable characters "[2;10H", would cause a Digital Equipment Corporation VT100 terminal to move its cursor to the 10th cell of the 2nd line of the screen. Several standards exist for these sequences, notably ANSI X3.64. But the number of non-standard variations in use is large, especially among printers, where technology has advanced far faster than any standards body can possibly keep up with.
These 65 control codes were carried over to Unicode. Unicode added more characters that could be considered controls, but it makes a distinction between these "Formatting characters" (such as the zero-width non-joiner) and the 65 control characters.
I'm exploring converting an existing MFC app from MBCS to Unicode, and I'm compiling a simple starter app in Unicode mode to check out how edit controls, for example, behave differently in Unicode/W or MBCS/A mode.
GetText() and SetText() are the getter/setter methods for the TControl.Caption and TControl.Text properties. You should not be calling the methods directly, use the properties instead. Some controls publish the Caption property, and some controls publish the Text property instead.
For versions 5.80 and later of comctl32.dll, common controls notifications support both ANSI and Unicode formats on Windows 95 systems or later. The system determines which format to use by sending your window a WM_NOTIFYFORMAT message. To specify a format, return NFR_ANSI for ANSI notifications or NFR_UNICODE for Unicode notifications. If you do not handle this message, the system calls IsWindowUnicode to determine the format. Since Windows 95 and Windows 98 always return FALSE to this function call, they use ANSI notifications by default.
In Cambodia, we need to use Khmer font to show our own language characters. ArcGIS Pro which has Ribbon interface support the display of the Khmer font but we need to change the font to use Khmer font. I am wondering if it is possible to change font used by Ribbon controls and dialogues to the one that support our Khmer Unicode?
I found a solution, which involves changing the function and using the unicode for .
I think u12 is the unicode for the control character , because when you insert it literally () and you hit ga on it, the output is 18, Hex 12, Octal 022.
Edit: After reading Christian Brabandt's answer, I've realised that my solution was too complex.
As he has well explained, no need of unicode, a control character must simply be escaped in a string, so the proper way to write the function would be:
I would like to be able to input a non-printing control code in text, identically to the Insert Unicode Character choice when editing dimensions. Yet, I'm unable to use the same unicode characters (without cutting/pasting between dimensions and text). Doe Revit text NOT allow for the use of all Unicode format control codes and only printing ones?
It seems to me that the Revit application itself doesn't allow for input of Unicode FORMATTING codes from the keyboard and must be done, and only for dimensions, from the context menu. Is that correct? If so, that really should be changed to allow for industry standard input of all Unicode controls and characters directly from the keyboard. I know it works for printing characters from the keyboard, either in text or dimensions.
Following are my observations and findings while using Unicode in a LabVIEW UI application. The purpose of using Unicode in this application is to localize the UI on the fly in any language without having to change the Computer locale. The application provides a settings page which allows the user to select the language of the UI. Based on this setting all UI components (controls and indicators) are localized into the selected language. The resource strings for all controls/indicators and languages are read from a text file containing Unicode strings.
Disclaimer:
LabVIEW for Windows has limited support for Unicode strings in the front panel controls and indicators. This is not an offically supported feature, meaning that it is not as fully tested as other released parts of the development and run-time environment. In addition this feature is not covered under standard product support and parts of this feature may change in future releases of LabVIEW, i.e. any code developed on this feature may require changes when upgrading to a newer version of LabVIEW. If you have any feedback or questions about using Unicode in LabVIEW post them as comments on this document or in the Developer Zone discussion forums.
The LabVIEW string controls and indicators have two private properties related to entering and displaying Non-Unicode (extended ASCII) or Unicode characters. These properties are not exposed through the regular property node; access to these properties is provided through subVIs as part of the examples included with this document.
InterpretAsUnicode is a property which can be enabled on text elements of different UI controls and indicators, such as the text of a string control/indicator, the caption of a control/indicator, the Boolean text of a Boolean control/indicator, etc. This property controls whether a string value passed to the text element is interpreted as an ASCII or Unicode string. SubVIs provided with the example in this document allow you to pass strings to different UI elements and select whether you are passing an ASCII or Unicode string.
The Listbox, Multicolumn Listbox and Table controls have different behavior in terms of processing Unicode strings from the rest of the text elements described previously. These controls so not use the InterpretAsUnicode property. Instead they look for a BOM (Byte Order Mark) on any strings passed to them. If a string passed to these controls starts with a BOM (either 0xFFFE or 0xFEFF) then the string will be handled as Unicode. This allows you to mix both Unicode and ASCII strings in the same control. The examples include subVIs to pass strings to these controls and mark them as Unicode using the BOM.
The attached project includes a number of examples showing how to display Unicode strings on different UI controls and indicators. For each of these control types subVIs are included to pass strings to the control and their caption and specify whether the string should be treated as Unicode or not. The following UI controls and indicators are supported with specific VIs:
Using the VI server functions in LabVIEW (property nodes for VIs, controls, etc.) you can build your own Import/Export Strings functionality which could support Unicode for any parts of LabVIEW that does support Unicode.
This unicode is handy and all, but until it work or you have some way to make it work on the menu bar, it fall short of being a real solution for multiple langauge. in the western us we have a host of multi cutural people all looking at the same program. it would be nice if we could change it also on the fly to be a different langauge. or maybe a make a menu bar control that we use in place of it. that we could modifiy.
Having those prepared VIs is great, but I want to know how it's done. I can see that author uses xxx.InterpAsUnicode property but I fail to find it in my environment even after enabling unicode in *.ini file. I don't know how to enable that property
For Unicode support these are the only two relevant properties. Using the property nodes from the existing examples you can now use these properties on other controls as well if they are availbale for these
When you say "I have my labview setup so I can copy chinese characters out of my worksheet and paste directly into a frontpanel text box", I assume that means you followed the instructions on this document to enable Unicode in LabVIEW controls. While the UseUnicode token allows to support the display of Unicode text in LabVIEW, it has its limitation and doesn't make LabVIEW a fully Unicode compliant application. What it allows is to render a Unicode string properly on screen, but it doesn't guarantee that the LabVIEW string manipulation functions will work, nor any toolkit functions like the Report Generation Toolkit. That's why this feature is private and unsupported.
