When I'm using AucTex, I tend to have problems with how the package formats the fonts I use within tags such as \textit{}. It appears that AucTeX wants to display an italicized version of the buffer's font, but if it does not exist, I get some garbage characters. [Emacs AucTeX font bug Is there some way I can prevent AucTeX from requesting a non-existent italic version of the font I'm using when I use these commands?


Put your cursor on the text in question and do C-u C-x =. Near the bottom of buffer *Help* you will see the name of the face used for that text. Use M-x customize-face FACE, where FACE is that face name.
