No, you don't need to. The only time the encoding of the strings is
important is when you're passing them to external code as a C-style char*
pointer. Or at least it should be.

I agree, it should be; it's not, however. For instance, under 5.8.8, a
string containing "\xc1" (capital A acute) will match /\w/ if it is
utf8-encoded and not if its not. I'm not sure if this is fixed in 5.10;
I'm not sure, either, what the correct fix would be.
