Detailed Description

CYAML functions for handling utf8 text.

Function Documentation

cyaml_utf8_casecmp()

int cyaml_utf8_casecmp	(	const void *const	str1,
		const void *const	str2
	)

Case insensitive comparason.

Note

This has some limitations and only performs case insensitive comparason over some sectons of unicode.

Parameters

[in]	str1	First string to be compared.
[in]	str2	Second string to be compared.

Returns

0 if and only if strings are equal.

cyaml_utf8_get_codepoint()

unsigned cyaml_utf8_get_codepoint	(	const uint8_t *	s,
		unsigned *	len
	)

Get a codepoint from the input string.

Caller must provide the expected length given the first input byte.

If a multi-byte character contains an invalid continuation byte, the character length will be updated on exit to the number of bytes consumed, and the replacement character, U+FFFD will be returned.

Parameters

[in]	s	String to read first codepoint from.
[in,out]	len	Expected length of first character, updated on exit.

Returns

The codepoint or 0xfffd if character is invalid.
