"The Text Layout Framework is deprecated and the functionality will be unavailable with Flash Professional CC. If a FLA file containing TLF Text, previously saved with an older version of Flash Professional, is opened with Flash Pro CC, then TLF is converted to Classic Text. For more information, see this article."
Okay.
And now what?? we need to use Arabic(Hebrew...) fonts, are we stuck with Flash CS6 for ever??
I used a trick and it works
1- Copy two (.swc) files from flash cs6 or cs5 (support tlf text)
textLayout.swc
tlfruntime.swc
2- Paste them into( Adobe Flash CC \Common\Configuration\ActionScript 3.0\libs)
3- Restart flash
4- Use the TLFTextField method
import fl.text.TLFTextField;
var txt:TLFTextField = new TLFTextField ;
txt.text = "النص العربي";
addChild(txt);
5- Make sure to embed font to the library .
There are few working solutions to this like text classes and extensions but one easy way is to keep Flash Cs5 or 6 installed and make texts on it then import them as swf files.
