Determines if a character is typically rendered in a double-width
cell under legacy East Asian locales. If a character is wide according to
g_unichar_iswide(), then it is also reported wide with this function, but
the converse is not necessarily true. See the
Unicode Standard Annex [11|11]
for details.
If a character passes the g_unichar_iswide() test then it will also pass
this test, but not the other way around. Note that some characters may
pass both this test and g_unichar_iszerowidth().
