Beet update command ignores my replace setting

Hi there,

in the latest version of beets, when using beet update command (since I delete files from disc from time to time) I noticed that my tags are being repopulated with special characters. At import I use a series of replace strings in the configuration file to remove all special characters not being read properly on systems with ut8.

Now, if I issue beet update command my missing files are being deleted but all my other files do get the titles with special characters back.

is there any way to make beet update take in consideration my replace strings in config file ?

thanks

Reproduce the issue with `beet update` using the provided configuration and `replace` rules, then trace the update command's metadata and replacement handling. Done means update preserves the configured replacements instead of restoring special characters; verify with the supplied Windows/Python setup or an equivalent focused test.
