Access a font's unicode range

Jun 26, 2012 2:42 PM

Tags: #font #actionscript #actionscript_3.0

Hello,

 

Is it possible to access a font (local, not embeded) and fill an array with every unicode character present within the font?

 

I'm thinking in terms of this as a tool similar to how Illustrator's glyphs panel works. You select a font and get a list of all the Glyphs in the font.

 

Thanks for any help,

Cameron

    Try font.hasGlyphs.  Not sure if it works on device fonts or not.

    Looks like it doesn't solve my particular use case, but it's a step closer than I was before. Thanks for the input.

    The Font class is used to manage embedded fonts in SWF files. Embedded fonts are represented as a subclass of the Font class. The Font class is currently useful only to find out information about embedded fonts; you cannot alter a font by using this class. You cannot use the Font class to load external fonts, or to create an instance of a Font object by itself. Use the Font class as an abstract base class.

    You could try capturing a bitmap of each glyph and see what is in the bitmap.

    Interesting thought. I'll have to look into that.

    Also possiblity is rendering it in a TextField and see if missing glyphs report a textWidth of 0 or some other tell-tale value.

    Sounds like a good idea. Is there a high performance way to do this? Prior to this thread I tried something vaguelly similar. I wanted to fill an array by testing every unicode between 0 and 6xxxxx (I have unicode characters on the private range in a custom font). Doing this crashed the browser I was using to test swf.

     

    Is there a reasonable way to test 60k+ characters? I'm not entirely sure the lenth of full unicode list, but I know my characters were getting 60k values from charCodeAt()
