> Lucy::Util::StringHelper provides two types of routines. First, there are
> miscellaneous string manipulation routines such as overlap() and to_base36().
> Second, there are UTF-8 helper routines: utf8_valid(), encode_utf8_char(),
> decode_utf8_char(), is_whitespace(), and back_utf8_char().
> The UTF-8 utilities are primarily used by CharBuf, and it may make sense to
> either move them into CharBuf.c or publish them as static inline functions so
> that CharBuf can optimize around them -- particularly encode_utf8_char() and
> decode_utf8_char(). However, they are also needed other places within the
> core - e.g. any class that reads character data from the index will need to
> check UTF-8 validity.
