Character style in code

Hey, has anyone ever used TextMesh Pro and tried to change specific characters style? like put a character bold, but by using code instead of rich text?

I am not being able to do it:
exampleChar.style = FontStyles.Bold;
exampleChar.scale *= 5;

This doesnt work, I though it might be necessary for me to update geometry or something but It doesnt work either.
Thanks in advance
