[Mediawiki-l] After upgrade to 1.17 problems with templates with german umlauts

[Norbert Schneider]

Hi,

after upgrade from 1.16.5 to 1.17.0 all my entries based on templates with german umlauts disappeared.

Example:
Template:Täglich is changed to Template:Täglich 

I can't find the reason. Database link problem? Database table templatelinks is unchanged. In the editor the entry {{Template:Täglich}} is displayed correctly.
  
Produkt	Version
MediaWiki 1.17.0
PHP	5.3.3 (apache2handler)
MySQL	5.1.52
Centos 5.6

Many thanks for your help.

Norbert
