A multibyte character is a sequence of one or more bytes representing the code unit sequence for an encoded character of the execution character set.
A null-terminated multibyte string, or ntmbs, is an ntbs that constitutes a sequence of valid multibyte characters, beginning and ending in the initial shift state.146
A static ntmbs is an ntmbs with static storage duration.
An ntbs that contains characters only from the basic literal character set is also an ntmbs.
Each multibyte character then consists of a single byte.
