utf8strblen()

Find the number of UTF-8 characters in part of a string

Synopsis:

#include <utf8.h>

int utf8strblen( char const *text, 
                 int max_bytes, 
                 int *bytes );

Arguments:

text

A UTF-8 string.

max_bytes

The maximum number of bytes to count.

bytes

A pointer to a location where utf8strblen() stores the number of characters in the specified portion of the string.

Library:

Description:

The utf8strblen() function returns the number of UTF-8 characters made up of max_bytes bytes in the string text, and sets bytes to the number of bytes used to compose the number of UTF-8 characters returned.

The bytes argument won't equal max_bytes if there are fewer than max_bytes bytes in the string, or if the last byte doesn't fall at the end of a UTF-8 character.

Returns:

The number of UTF-8 characters made up of max_bytes bytes in the string text.
