for me (win xp) Verdana doesn't contain those glyphs. try another font, maybe
Lucida sans unicode.
and is your flex/flash builder file encoding utf-8?
Thank you for replying.
PaulH, I'm on a Mac, and all those Unicode characters show up fine in Verdana for me. Yes, my Flex project is encoding in UTF-8
rgadiparthi, Thanks for the link. That will be a useful tool.
I have experimented a bit more since my original post and still can't get those glyphs to embed. No errors occur, they just don't show up.
The existence of Unicode characters in my font is still a point of confusion. I have pasted a few of the UTF-8 characters in the U+2100 range into text editors and specified to display all text in Verdana font, and the characters show up. Then I opened Mac OS's Character Palette and looked at that UTF-8 character range, and it does not show Verdana as having those characters available. I wonder if the text editors are doing some kind of background font replacement?
Next step was to embed a different font into my Flex app. I chose Arial since the Character Palette said it did have the Unicode range I was interested in, and I was able to paste the arrow characters into my Flex app. So, I guess that is the final verdict - the Verdana font doesn't have the glyphs I need even though they show up in text editors when formatted as Verdana.
