Unicode is not directly concerned with the validity of strings as
such. A single byte containing the hex value 00 will occur
frequently within typical UTF-16 text (most notably for all
characters in ISO-Latin-1, and for two common characters--the
space and the ideogram for "one"--in Chinese). However, a string
terminated by a pair of 00 bytes (aligned to the character
boundary), in other words a NULL represented in its UTF-16 format,
is not unheard of as a terminator--Windows, at least, uses that
for its "wide character" string format.
