** File: mbcs.c
**
** Synopsis: mbcs {dirName}
**
** where dirName is the directory to be traversed. dirName is required.
**
** Description:
** mbcs.c tests use of multi-byte characters, as would be passed to
** NSPR funtions by internationalized applications.
**
** mbcs.c, when run on any single-byte platform, should run correctly.
** In truth, running the mbcs test on a single-byte platform is
** really meaningless. mbcs.c, nor any NSPR library or test is not
** intended for use with any wide character set, including Unicode.
** mbcs.c should not be included in runtests.ksh because it requires
** extensive user intervention to set-up and run.
**
** mbcs.c should be run on a platform using some form of multi-byte
** characters. The initial platform for this test is a Japanese
** language Windows NT 4.0 machine. ... Thank you Noriko Hoshi.
**
** To run mbcs.c, the tester should create a directory tree containing
** some files in the same directory from which the test is run; i.e.
** the current working directory. The directory and files should be
** named such that when represented in the local multi-byte character
** set, one or more characters of the name is longer than a single
** byte.
