unicode-range: U+1780-U+17FF, U+19E0-U+19FF;
</mx:Style>
I don't know how to solve this problem?

Answer 1

Unicode is not the same as UTF-8, as Unicode consists of 2 bytes for each character whereas utf-8 only uses 2 bytes for special characters.
So the fist question is, have you entered unicode (2byte characters) or utf-8 special characters entered into the text field?
Can you post the character codes you have entered and seen this behavior?
Next you should make sure you get the correct data from the DB. To do this you can debug your code and set a breakpoint right after you get the data from the DB (I guess into a string variable), the check the string using the data inspector. Look at the bytes, not at the string itself (open the string node to see the internal representation).
