massive find/replace on MySQL db

Hello, I've inherited a MySQL db (4MB on disk) that's riddled with inconsistent storage of character entities from being pasted from Word. At very least I hope to convert all quotes "‘" - "”" to HTML's """ and "'". I imagine I'll run a big query, save the id's needing edit in a file than have a script hit all those, pulling text/varchar fields, using strtr() to make changes and updating. I suppose I could have the script just do the 1st 10 in the file, remove those from the file, then I'd recall the script. I imagine this might take 10/20 minutes. Am I missing some internal MySQL feature that would do this? Hmm, what about running strtr() on a mysqldump-ed file? Any advice/links appreciated. Please CC me. Thanks a lot!
