mysql: Unknown OS character set 'ISO-8859-15'

[Donzi.UTzone]

Das Problem:
MySQL kennt die Sprache ISO-8859-15 nicht.

Beim Upgrade von MySQL von 5.1 auf 5.5 wird man beim Starten mit folgendem in der Shell überflutet:

/usr/bin/mysql: Unknown OS character set 'ISO-8859-15'.
/usr/bin/mysql: Switching to the default character set 'latin1'.
/usr/bin/mysql: Unknown OS character set 'ISO-8859-15'.
/usr/bin/mysql: Switching to the default character set 'latin1'.
/usr/bin/mysql: Unknown OS character set 'ISO-8859-15'.
/usr/bin/mysql: Switching to the default character set 'latin1'.
/usr/bin/mysql: Unknown OS character set 'ISO-8859-15'.
/usr/bin/mysql: Switching to the default character set 'latin1'.
/usr/bin/mysql: Unknown OS character set 'ISO-8859-15'.
/usr/bin/mysql: Switching to the default character set 'latin1'.
/usr/bin/mysql: Unknown OS character set 'ISO-8859-15'.
/usr/bin/mysql: Switching to the default character set 'latin1'.
/usr/bin/mysql: Unknown OS character set 'ISO-8859-15'.
/usr/bin/mysql: Switching to the default character set 'latin1'.

Einfach unterbrechen und die Sprache des OS neu einstellen.
Wählt einfach de_DE.ISO-8859-15 ab, das ist alles.
