Thread:Project:Support desk/Pagetitle encoding eroblems when upgrading a wiki/reply (3)

Hi,

I have try this : ALTER TABLE `archive` CHANGE `ar_title` `ar_title` BLOB; ALTER TABLE `archive` CHANGE `ar_title` `ar_title` TEXT CHARACTER SET utf8 COLLATE utf8_bin;

And MySQL respond:
 * 1) 1170 - BLOB/TEXT column 'ar_title' used in key specification without a key length
