Tilde Symbol
Cre Wallace
The tilde was originally one of a variety of marks written over an omitted letter or several letters as a scribal abbreviation (a "mark of contraction").[3] Thus, the commonly used words Anno Domini were frequently abbreviated to Ao Di, with an elevated terminal with a contraction mark placed over the "n". Such a mark could denote the omission of one letter or several letters. This saved on the expense of the scribe's labor and the cost of vellum and ink. Medieval European charters written in Latin are largely made up of such abbreviated words with contraction marks and other abbreviations; only uncommon words were given in full.

In dominio sunt tres carucae et decem servi et triginta villani et viginti bordarii cum sedecim carucis. Ibi duodecim acrae prati et quindecim acrae silvae. Pastura tres leugae in longitudine et latitudine. Reddit quattuor et viginti libras ad pensam. Huic manerio est adjuncta Blachepole. Elwardus tenebat tempore regis Edwardi pro manerio et geldabat pro dimidia hida. Terra est duae carucae. Ibi sunt quinque villani cum uno servo. Valet viginti solidos ad pensam et arsuram.

On typewriters designed for languages that routinely use diacritics (accent marks), there are two possible solutions. Keys can be dedicated to precomposed characters or alternatively a dead key mechanism can be provided. With the latter, a mark is made when a dead key is typed, but unlike normal keys, the paper carriage does not move on and thus the next letter to be typed is printed under that accent. Typewriters for Spanish typically have a dedicated key for / but, as Portuguese uses / and /, a single dead-key (rather than take two keys to dedicate) is the most practical solution.
ISO 646 and ASCII incorporated many of the overprinting lower-case diacritics from typewriters, including tilde. Overprinting was intended to work by putting a backspace code between the codes for letter and diacritic.[8] However even at that time, mechanisms that could do this or any other overprinting were not widely available, did not work for capital letters, and were impossible on video displays, with the result that this concept failed to gain significant acceptance. Consequently, many of these free-standing diacritics (and the underscore) were quickly reused by software as additional syntax, basically becoming new types of syntactic symbols that a programming language could use. As this usage became predominant, type design gradually evolved so these diacritic characters became larger and more vertically centered, making them useless as overprinted diacritics but much easier to read as free-standing characters that had come to be used for entirely different and novel purposes. Most modern fonts align the plain ASCII "spacing" (free-standing) tilde at the same level as dashes, or only slightly higher.
In more recent digital usage, tildes on either side of a word or phrase have sometimes come to convey a particular tone that "let[s] the enclosed words perform both sincerity and irony", which can pre-emptively defuse a negative reaction.[18] For example, BuzzFeed journalist Joseph Bernstein interprets the tildes in the following tweet:
Among other uses, the symbol has been used on social media to indicate sarcasm.[19] It may also be used online, especially in informal writing such as fanfiction, to convey a cutesy, playful, or flirtatious tone.[20]
This decision avoided a shape definition error in the original (6.2) Unicode code charts:[31] the wave dash reference glyph in JIS / Shift JIS[32][33] matches the Unicode reference glyph for U+FF5E FULLWIDTH TILDE,[34] while the original reference glyph for U+301C[31] was reflected, incorrectly,[35] when Unicode imported the JIS wave dash. In other platforms such as the classic Mac OS and macOS, 0x8160 is correctly mapped to U+301C. It is generally difficult, if not impossible, for users of Japanese Windows to type U+301C, especially in legacy, non-Unicode applications.
The current Unicode reference glyph for U+301C has been corrected[35] to match the JIS standard[41] in response to a 2014 proposal, which noted that while the existing Unicode reference glyph had been matched by fonts from the discontinued Windows XP, all other major platforms including later versions of Microsoft Windows shipped with fonts matching the JIS reference glyph for U+301C.[42]
The JIS / Shift JIS wave dash is still formally mapped to U+301C as of JIS X 0213,[43] whereas the WHATWG Encoding Standard used by HTML5 follows Microsoft in mapping 0x8160 to U+FF5E.[44] These two code points have a similar or identical glyph in several fonts, reducing the confusion and incompatibility.
A tilde is also used in particle physics to denote the hypothetical supersymmetric partner. For example, an electron is referred to by the letter e, and its superpartner the selectron is written ẽ.
In the D programming language, the tilde is used as an array concatenation operator, as well as to indicate an object destructor and bitwise not operator. Tilde operator can be overloaded for user types, and binary tilde operator is mostly used to merging two objects, or adding some objects to set of objects. It was introduced because plus operator can have different meaning in many situations. For example, what to do with "120" + "14" ? Is this a string "134" (addition of two numbers), or "12014" (concatenation of strings) or something else? D disallows + operator for arrays (and strings), and provides separate operator for concatenation (similarly PHP programming language solved this problem by using dot operator for concatenation, and + for number addition, which will also work on strings containing numbers).
The presence (or absence) of a tilde engraved on the keyboard depends on the territory where it was sold. In either case, computer's system settings determine the keyboard mapping and the default setting will match the engravings on the keys. Even so, it certainly possible to configure a keyboard for a different locale than that supplied by the retailer. On American and British keyboards, the tilde is a standard keytop and pressing it produces a free-standing "ASCII Tilde". To generate a letter with a tilde diacritic requires the US international or UK extended keyboard setting.
The dominant Unix convention for naming backup copies of files is appending a tilde to the original file name.It originated with the Emacs text editor[64] and was adopted by many other editors and some command-line tools.
Formally, the tilde is a symbol most often used to accent letters in words used in certain languages, such as in the Spanish seor. However, you might also see the tilde used sometimes in informal writing as well.
In informal writing, a tilde (or multiple tildes) may be used at the end of a sentence to indicate a speaker is intending to be playful or flirty. You are most likely to encounter this usage on social media or in fanfiction writing. For example, you might see a social media post that looks like this:
The LaTeX-like TAB sequence at the Julia REPL generates a sequence of two Unicode code points, one for the n and one for the tilde. KDE Konsole knows how to display that properly with the tilde above the n, and cut-and-paste preserves the two-code-point-sequence.
I think that shows that xterm is cheating by displaying the two-code-point sequence as the single code point for n-with-tilde, which (if I am reading Unicode FAQs correctly) is a legacy encoding of the grapheme.
But whether the Constitution really be one thing, or another, this much is certain - that it has either authorized such a government as we have had, or has been powerless to prevent it. In either case, it is unfit to exist.

Looking at the previews, almost all of them feature the high tilde so I think it isn't surprising that changing a few randomly wouldn't work. I found one which had the tilde in the middle but that appears to lack the $ sign so probably isn't a good choice.
I just tried US keymaps and it doesn't work either...I'll probably try some more fonts. Otherwise I'll just deal without the tilde...first time this happens to me, never had problems with keymaps heh.
thank you all for the help
Basically Dropbox is not showing me any green checkboxes on my folders or files and the computer has been a little slow to start and was making a slightly mechanical noise at one point yesterday. Also, I tried installing some HPIJS driver for my old HP printer and it wants to install on my external clone because it is telling me that the Mac Volume is not a valid OS. Brand spanking new 1 TB drive as of about 4 months ago.
The tilde symbol is usually associated with your Home folder/directory. Typically, the Dropbox folder is created under your Home folder too. The fact that it doesn't synchronize with its cloud-based counterpart could mean you have no Internet connection, or that this folder was created elsewhere, then placed where it currently is. Are you sure your volume isn't in target mode? Check in System Preferences under Startup which volume is selected to boot on.
the tilde symbol is OK if I see it in Finder? i mean, say for instance if I see all the folders on my Hard Drive listed with a tilde in front. I think you are saying that is OK - both for Finder for Folders on my HD /and/ for Dropbox, yes?
