Replace some uses of OUStringChar with string literals

(At least MSVC++ 14.14, aka Visual Studio 2017 version 15.7, apparently requires
`"\xDFFF"` to be written with a `u` prefix in the concatenated string literal

  u"\xD800" "\U000103FF" "\xDFFF" "A"

to avoid "error C2022: '57343': too big for character", so prefix all the
individual string literals in such concatenations, even if that should be
redundant.)
