Hi,
there are online services that look for a font from an image.

Windows API lets you install custom fonts.
Code:
AddFontResource ( "myFont.ttf" );
...
RemoveFontResource ( "myFont.ttf" );


Anyway, most people don't know that most fonts are copyrighted and their free usage is limited. I never heard about a game been denounced but it might happen, so ensure you have the proper rights for redistribution.

Salud!
