[Mediawiki-l] Problems updating mediawiki from 1.45 to a higher version, deutsche Umlaute are display as question marks

[Daniel von Garrel]

Hello.

I want to update a mediawiki from version 1.4.5 to 1.9. The upgrade
script "upgrade1_5.php" to convert the database to utf fails with message:

Warning: fopen(maintenance/archives/patch-interwiki-trans.sql): failed
to open stream: No such file or directory in
/var/www/mediawiki/includes/Database.php on line 1959
Could not open "maintenance/archives/patch-interwiki-trans.sql".

I've tried also to update to version 1.5.8. Here the "deutsche Umlaute"
are shown as question marks.

Thanks
