Hi,
I'm trying to use some unicode characters (symbols) as the text for buttons,
but some characters appear as a box.

These characters appear ok:
↑ - &#x2191; (up arrow)
↓ - &#x2193; (down arrow)
← - &#x2190; (left arrow)
→ - &#x2192; (right arrow)

But, the next ones appear as a box!!!
↵ - &#x21B5; (down-left arrow)
↨ - &#x21A8; (up-down arrow with bottom line)

Is there a list of supported characters in Android?

Rui

You can find the fonts that are part of Android in
<frameworks/base/data/fonts> in the open source repository.

Hi,

Thanks for the answer.
The characters I want to use are there, but when I use them a rectangle
appears where the character should be :(

I'm using the strings.xml to put the buttons text, like this:
<string name="arrow">&#x21A8;</string>

 and in the layout XML file I reference this text like this
<Button android:text="@string/arrow" ... />

I'm I doing something wrong? I suppose I'm not, because this method work
very well with the other characters.

Thanks,
Rui

Hi,

I'm sorry to insist on this, but I can't find an explanation for this
problem. The Droid Sans font, from Android framework, contains the unicode
character ⏏ (U+23CF), as the attached screenshot proves, but when I use it
as the text of a button (in the layout XML file with @android:text
attribute) what I see is a rectangle as you can see in the attached image.

Any ideias about this? What should I do?

Hi,

Replying to myself, again, I noticed that the font used in the phone (the
emulator) is not the ones in <frameworks/base/data/fonts>.
The character ☎ (U+2603) appear differently in the character map and in the
actual application. See the attached pictures.

So, the question is, where is the default font used in the the phone
applications?

Thanks,
Rui
