A unicode character can consume 0, 1 or 2 columns on the terminal. You
can use wcwidth() to detect that. 0-width characters are usually combining
characters (In unicode you can write ê as a single character, or as two
characters, one for the hat and one for "e".), double-width characters are
for example CJK ideographs, hangul, ...
