Serbian accented c

[utkuturk]

Hello, thank you for your work. It is awesome! Is there a way to write č this character? I could not did it. When I try writing \v{c} it gives a question mark in the place of the character.

Thank you for your work.

For an initial ad-hoc solution, you can try including this command to your preamble:
\usepackage[T1]{fontenc}
Unfortunately, it changes the default font, but it gets the job done and recognizes the upper v above the c character.
