Desktop app and unicode characters

Hey,
I am using Chr( 11165 )+Chr( 11167 ) in my app.
In some windows machines these characters simply show up as empty bars (chr is unavailable)
How can I be sure the characters are available ? and what options do I have to show up/down arrows ? (other than creating an icon)

Thanks
R

On Windows, characters will only show up if your current font supports that character. Looking at this link, very few fonts support the arrow you have chosen:

Here’s a different arrow with much better font support:

Thanks David. I’ll follow your advice.

are those unicode??? how do u put them on a bevelbutton??

Copy / Paste from the forum, they are characters.

&uXXX where XXX is the Hex value of the unicode character
sometimes you might have to change the fontname, I found “Menlo” seems to render most of what I have needed

Does Arial or System font show the characters??

try it

just try it with System and it work.

Just be aware that on macOS the font fallback system is different than on Windows and often when one font does not contain the glyph the system will fall back to a related font in a similar family that does. This does not occur on Windows in the same way so if the font doesn’t contain the glyph you may get different results.

it look nice on the mac osx on a pushbutton but look really ugly on window
