## #55169 — Stas Malyshev — 2011-09-04T05:13:04+00:00

Hi!

In my tests, I have some test failures in mbstring extensions, namely:

Bug #28220 (mb_strwidth() returns wrong width values for some Hangul 
characters) 
[/Users/smalyshev/php-src/branches/PHP_5_4/ext/mbstring/tests/bug28220.phpt]
Bug #49536 (mb_detect_encoding() returns incorrect results when 
strict_mode is turned on) 
[/Users/smalyshev/php-src/branches/PHP_5_4/ext/mbstring/tests/bug49536.phpt]
Unicode standard conformance test (ill-formed UTF sequences.) 
[/Users/smalyshev/php-src/branches/PHP_5_4/ext/mbstring/tests/illformed_utf_sequences.phpt]

The `mb_strwidth()` returns 8085 instead of 8101.
The `mb_detect_encoding()` returns false for both utf-8 examples and as 
far as I can see in the code of mbfl_filt_ident_utf8() it is intended 
result - this sequence is not considered valid utf-8.
For the illformed sequences I see many sequences that are supposed to be 
empty strings be 0000003f0000003f0000003f0000003f0000003f0000003f or 
more 3f's of different lengths.

Could you please check it out and see why these are failing?
