Regarding macrons
Some tags in the database seem to have macrons in them, which isn't so good since on top of being fundamentally dumb, they can make searching for tags a massive pain. So yeah, please avoid using them.
are they fixable through the UI or do I need to do it in the DB?
They can be fixed normally yeah, just a case of locating them really.
can probably do a search for all macrons. i'll check it out later.
