Not really, but still, there is nothing to fix here per my
previous comment.

Not sure if this is a bug or rather a feature request. Anyhow, I
guess it won't be fixed, since mbfl has no notion of combining
characters, generally, and the grapheme_*() functions already
cater to that. Furthermore, mb_strwidth() appears to be useful
for monospaced fonts only.

Description:
------------
combining characters should account for zero width when counted with mb_strwidth.
Test script:
---------------
<?php
$a = 'é';
echo mb_strwidth($a, 'utf8'), "\n";
$b = Normalizer::normalize($a, Normalizer::NFD);
echo mb_strwidth($b, 'utf8'), "\n";
Expected result:
----------------
1
1
Actual result:
--------------
1
2
------------------------------------------------------------------------
