I'm not sure whether I really get the issue, but as it seems the
problem seems to be that PHP is using locale-aware lowercasing
functions in the core. Couldn't the issue be fixed by replacing those
with local-unaware functions? Why does one have to change PHPs general
case sensitivity handling for that?
