I have begun the process of cleaning up all the character encoding problems that we see in older posts.
The foreign language posts which were completed unrecoverable are being deleted.
Damaged characters in English posts are being corrected via a search and replace function in the database, which must be executed methodically and carefully so as to not ruin the database (of course backups are made).
If you made a post in the past that became corrupted, and it was for instance a quote in a foreign language which was ruined but the rest of the post in English is fine, please supply me with the link to the post and the correction if you have a chance (last time I asked a whopping zero people responded though).
Hopefully soon the older posts will be fixed and look nice again
