[Mediawiki-l] ERROR 1071

[david]

Hi, I'm trying to save a dead wiki (well, what's dead is the server)
from a db dump.

It was an old version (MW 1.10).
After importing the dump the wiki works but with the page titles
corrupted (accents and other special characters).
After following this...
http://www.mediawiki.org/wiki/Manual:Backing_up_a_wiki#Character_set
... to change from latin-1 to UTF-8; mysql give me an error when I try
to import to a new database:

ERROR 1071 (42000) at line 340: Specified key was too long; max key
length is 1000 bytes

Well, I don't know what I can do to arrange that.
Any idea? (please for dummies if possible, step by step :)

thanks in advance
