Text input: when entering keys like OemOpenBrackets, OemCloseBrackets, OemTilde and possibly others, the first key press is ignored and then it works fine.
(empty) containers become unlocalized. You can get around this by adding an "(empty)" variant in entitynames but this is hardly ideal.
*UPDATE* However, some templates like "{X}'s Corpse" are undesirable. Keeping "Bandit" and "Bandit's Corpse" as separate lines allows for better translation.
