Tamil dotted circle in Flash

I'm making an AIR application that displays a quiz created in a back-office. Everything is fine with any language: the questions' TextFields, even when wrapping, do not "hyphenate".

When displaying a Tamil text, the questions show a little dotted circle at automatic carriage returns (I can't read Tamil and I can't find anyone around me who can). I believe this is the equivalent to hyphens in occidental alphabets.

I have two questions:

Is this a problem that these circles appear in a text (even if they are not present in the back-office)? Is it an error, is it just ugly, is it totally normal and good-pratice?

Does someone know how to get rid of them?

This problem appears when the font is not embedded and when using the TextField class. If the font is embedded the problem disappears but other misinterpretations of Tamil characters occur.

Conclusion: TextField does not support Tamil language (am I the first one to notice that???). The only solution is to switch to TLFTextField (available as a swc with Flash). Don't forget to embed the font as CFF when using TLF.
