Description

testIsUtf8WithMbstring is failing in PHP 5.4.10 with the strings:

  • "\xf8\x88\x80\x80\x80" (#6)
  • "\xfc\x84\x80\x80\x80\x80" (#7)
  • "\xf7\xbf\xbf\xbf" (#11)
  • "\xfb\xbf\xbf\xbf\xbf" (#12)
  • "\xf4\x90\x80\x80" (#18)

mb_check_encoding( $string, 'UTF-8' ) is returning false in php 5.4.10 (they made their checks stricter?)

Hashar, I'm assigning this to you as 750db30d9 author.

Did it succeed with a previous 5.4 release or did it start failing with 5.4.10 ?

I do not yet have time to look at this for now, I guess we want our test to react differently whenever PHP is 5.4 or later.

This happens for me on PHP 5.4.4-14 (Debian).
Most likely this item from the PHP 5.4.0 NEWS file indicates the change: Ill-formed UTF-8 check for security enhancements. (Rui)

Both patches mentioned here have received -1's and likely need rework.
