While I understand the dangers of such a feature, I too would love to be able to do a global find a replace across a database.
I have a database with 3,000+ notes I imported from a program called Scholar’s Aid. In the process of exporting those notes into rtfs, all of the Spanish language diacritics were switched in a systematic way. é became È, í became Ì, and so on. Since I don’t otherwise use the characters È, Ì, Ò, Û, and others, it would seem useful to just do a global find a replace for each of them instead of going file by file as I currently do.
