modifying a font style

[Anceane]

I use actually the old addons Pawksickles for that, but there is some addons that simply dont let the style of a font be change, so i would like to know if there is a way to go directly in an addon and change the name of the style of the font to suppress all the shadow, outline, bold and more just to be normal ?

what line or code should i seach for ?

(I have a lot of difficulty to read text with shadow for example and even if i put the size large enough, the shadow for example still add trouble for me).

I do not name addons in particular, as if i can do it myself with your help, the addon author would have less to do.

Thank you
