characterValue property accept the Glyph ID values too... try the approach.
I don't think the bullet characters will show up in the contents unless you convert them to text first.
It looks like these will work to supply a unicode ID number for the character you want:
paragraphStyle.bulletChar.characterValue = 0x200B;
paragraphStyle.bulletChar.characterValue = 8203;
Hi all and thank you for inputs,
@imagine > yes but zero width character seems to have the regular space glyph code. So problem is that in this case, I will end up with a regular space creating an indent in the beginning of the line. Unless I am wrong.
@absqua > Great !!! It works fine. I tried to set unicode value but the wrong way.
Thanks you again for all of you.
