You should set those to something other than C. It doesn't matter much
what exactly, so what you have there is fine.
Setting it to C would for example affect the ability of the text search
functionality to detect words containing non-ASCII characters.
Doesn't searching LIKE 'abc%' behave much better for C than others. This was the driving force for choosing C for us.
