`numCharacters` overloads

== Synopses

Declared in `<bdlde_utf8util.h>`

Return the number of Unicode code points in the specified `string`. `string` is necessarily null‐terminated, so it cannot contain embedded null bytes. The behavior is undefined unless `string` contains valid UTF‐8. Note that `string` may contain less than `bsl::strlen(string)` Unicode code points.

Return the number of Unicode code points in the specified `string` having the specified `length` (in bytes). `string` need not be null‐terminated and can contain embedded null bytes, and `string` may be null if `0 == length` (see {Empty Input Strings}). The behavior is undefined unless `string` contains valid UTF‐8. Note that `string` may contain less than `length` Unicode code points.
