*Help* Bold and italic words for translations

[JBunny]

Hello everybody !
I don't know if this topic should be posted here but here we go.

 

I'm translating a couple of Mods and I want to put some sentences to appear in italic or bold in-game. Does anyone know how to do it? Is there a tutorial for this kind of things?
I'm new at translating and so far I've only learned how to change the gender of some pronouns (For example: {0.he}{0.him} ).
I've searched on Google but I haven't found anything...
Any help is welcome.
Thanks in advance?
