Bug #69267 [Com]: mb_strtolower fails on titlecase characters

Edit report at https://bugs.php.net/bug.php?id=69267&edit=1 ID: 69267 Comment by: z dot figura12 at gmail dot com Reported by: z dot figura12 at gmail dot com Summary: mb_strtolower fails on titlecase characters Status: Open Type: Bug Package: mbstring related Operating System: Kubuntu 14.10 PHP Version: 5.5Git-2015-03-20 (Git) Block user comment: N Private report: N New Comment: After looking, there are actually two parts to this bug. One part is in PHP, and I was easily able to locate the error. However, this only fixed the characters Dž, Nj, Lj, Dz, whereas Greek characters with hypogegrammene were still broken. The second part was traceable back to OpenLDAP. I have submitted a patch there and hope to see it accepted. I am not sure how to propagate this change to PHP, however.

Test script: --------------- echo mb_strtolower("ᾼ"); Expected result: ---------------- ᾳ Actual result: -------------- ᾼ ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=69267&edit=1
