The following assert fails, but should not.

assert(!inPattern('a', "äöüa-z"));

The problem is the combination of "foreach (size_t i, dchar p; pattern)" with
"i + 1 < pattern.length". Due to foreach "i" is the index of the code point,
but the comparison assumes an index of code unit. The pattern string consists
of 6 code points, but 9 code units.
