I have a simple question that I can't find anywhere over the internet, how can I convert UTF-8 to ASCII (mostly accented characters to the same character without accent) in C using only the standard lib? I found solutions to most of the languages out there, but not for C particularly.
Thanks!
EDIT: Some of the kind guys that commented made me double check what I needed and I exaggerated. I only need an idea on how to make a function that does: char with accent -> char without accent. :)

Each character is represented by one to four bytes. UTF-8 is backward-compatible with ASCII and can represent any standard Unicode character. The first 128 UTF-8 characters precisely match the first 128 ASCII characters (numbered 0-127), meaning that existing ASCII text is already valid UTF-8.
For characters represented by the 7-bit ASCII character codes, the UTF-8 representation is exactly equivalent to ASCII, allowing transparent round trip migration. Other Unicode characters are represented in UTF-8 by sequences of up to 6 bytes, though most Western European characters require only 2 bytes3.
Most C string library routines still work with UTF-8, since they only scan for terminating NUL characters.
Take a look at libiconv. Even if you insist on doing it without libraries, you might find an inspiration there.
