utf32_t ub_get_next_char_utf16	(	const utf16_t *	s,
		size_t	len,
		size_t *	ip
	)

Gets the next Unicode character in a UTF-16 sequence.

The index will be advanced to the next complete character, unless the end of string is reached in the middle of a UTF-16 surrogate pair.

Parameters:

[in]	s	input UTF-16 string
[in]	len	length of the string in words
[in,out]	ip	pointer to the index

Returns:

the Unicode character beginning at the index; or EOS if end of input is encountered

utf32_t ub_get_next_char_utf32	(	const utf32_t *	s,
		size_t	len,
		size_t *	ip
	)

Gets the next Unicode character in a UTF-32 sequence.

The index will be advanced to the next character.

Parameters:

[in]	s	input UTF-32 string
[in]	len	length of the string in dwords
[in,out]	ip	pointer to the index

Returns:

the Unicode character beginning at the index; or EOS if end of input is encountered

utf32_t ub_get_next_char_utf8	(	const utf8_t *	s,
		size_t	len,
		size_t *	ip
	)

Gets the next Unicode character in a UTF-8 sequence.

The index will be advanced to the next complete character, unless the end of string is reached in the middle of a UTF-8 sequence.

Parameters:

[in]	s	input UTF-8 string
[in]	len	length of the string in bytes
[in,out]	ip	pointer to the index

Returns:

the Unicode character beginning at the index; or EOS if end of input is encountered
