There's a class of characters in the Unicode character set, called the
"CJK Ambiguous Width Character set". For these characters the width
returned by the wcwidth/wcswidth function is usually 1. This is often a
problem in East-Asian languages, which historically use character sets in
which these characters have a width of 2. By default, the wcwidth/wcswidth
functions return 1 as the width of these characters, except if the language is
specifed as "ja" (Japanese), "ko" (Korean), or "zh" (Chinese). In these
languages wcwidth and wcswidth return 2 for these characters. This is not
correct in all circumstances, so the user of one of these languages can specify
the modifier "@cjknarrow", which modifies the behaviour of wcwidth/wcswidth to
return 1 for the ambiguous width characters.</para>
