Thread:Project:Support desk/1.17, 1.18, 1.19, 1.20, 1.21 Critical bug - lack of translation of page name to suitable encoding - whole site is broken by update scripts (not updated)/reply (5)

I found that I am probably using https://drupal.org/node/198184 Garbled text - it looks that 1.17 not support conversion for "garbled" or I do not know how to trigger it?

Still I have not idea what to do to migrate?
