the main problem I found is the bold or italic parameter are always applied to the whole text, and not only a word or two.
how do I find:
-character height that is used in a textmesh (and also line spacing)?
-how many character it will fit if I have a TextMesh with x pixels/meters as width?
I'm thinking of just create several TextMesh and rearrange them so it would look like 1 big TextMesh, but actually compromised of several small TextMesh.
