Multibyte character support

Support for multibyte characters includes support for wide characters. Generally, wide characters are permitted anywhere multibyte characters are, but they are incompatible with multibyte characters in the same string because their bit patterns differ. Wherever permitted, you can mix single-byte and multibyte characters in the same string.

Note: You must specify the -qmbcs option to use multibyte characters anywhere in your program.

In the examples that follow, multibyte_char represents any string of one or more multibyte characters.
