after updating to 2.8.1 special characters are not shown properley on my page. German ue=ü, ae=ä, oe=ö are all presented as ? in a black rhombus.
I have some installations in 2.7.2 still, everything is fine there! Not so in same Pages on 2.8.1.
All Installations are run on same server (Linux), all DB also on same Server, everything is equal setting for both 2.7. and 2.8. (DB-collation, PHP-version ...)
Pages showing this behavior are self-Programmed pages, that lookup values from mdl_user table. Equal pages show different behavior on both versions, What has happened during the update, that makes this appear???
Please some help, what I can do.
Thanks a lot
