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.
