Use the -qmbcs option if your program contains multibyte characters. The -qmbcs option is equivalent to -qdbcs.
See also #pragma options.
Multibyte characters are used in certain languages such as Chinese, Japanese, and Korean.
Multibyte characters are also permitted in comments, if you specify the -qmbcs or -qdbcs compiler option.
If a source file contains multibyte character literals and the default -qnombcs or -qnodbcs compiler option is in effect, the compiler will treat all literals as single-byte literals.
To compile myprogram.c if it contains multibyte characters, enter:
xlc myprogram.c -qmbcs
