Embed fonts viewing issue

Hello,
I have embeded some special font Helvetica Neue, getting data from xml file with UTF-8 encoding set. When I type directly into dynamic textField special symbols (latvian, lithuanian language) it shows them correctly, but when publishing, special characters are missing. The best is that Flash is not replacing those special symbols with some substitute fonts while typing directly, it shows them in Helvetica Neue font. For test I done this with default Arial font and everything was fine when published. While testing TextFields glypths are set to embed all. Is there any solution?
Thank you
