For a couple of months ago I publish a post about fonts embed with unicode range. There are ways on how to extract the fonts from Flash files with some de-compiling but for those who found the article interesting but never figured out the unicodeRange bit, well there is a solution.
The AIR Unicode app is used to create the correct unicode range to optimize the amount of bytes that is needed to be loaded. To get the range it’s really simple.
1.) Copy/Paste your entire XML file to the input field (top field)
2.) Select font to use and set class name.
3.) Press convert
4.) Copy/Paste the unicodeRange to the Flex Project that creates the font file.
