There are uses of toLowerCase where toLocaleLowerCase might be more appropriate, e.g. when used in combination with localeCompare [1].
We should change these toLowerCase [2] calls to toLocaleLowerCase to make sure we catch edge-cases that seem to exist according to MDN [2].
There seemed to have been concerns [4] that this might impact performance, so maybe we should try to figure out if and if yes how severe they are.
