static Fallback::mb_strlen	(	$	str,
		$	enc = ''
	)		[static]

Fallback implementation of mb_strlen, hardcoded to UTF-8.

Parameters:

string	$str
string	$enc	Optional encoding; ignored

Returns:

int

static Fallback::mb_strpos	(	$	haystack,
		$	needle,
		$	offset = 0,
		$	encoding = ''
	)		[static]

Fallback implementation of mb_strpos, hardcoded to UTF-8.

Parameters:

string	$haystack
string	$needle
string	$offset	Optional start position
string	$encoding	Optional encoding; ignored

Returns:

int

static Fallback::mb_strrpos	(	$	haystack,
		$	needle,
		$	offset = 0,
		$	encoding = ''
	)		[static]

Fallback implementation of mb_strrpos, hardcoded to UTF-8.

Parameters:

string	$haystack
string	$needle
string	$offset	Optional start position
string	$encoding	Optional encoding; ignored

Returns:

int

static Fallback::mb_substr	(	$	str,
		$	start,
		$	count = 'end'
	)		[static]

Fallback implementation for mb_substr, hardcoded to UTF-8.

Attempts to be at least _moderately_ efficient; best optimized for relatively small offset and count values -- about 5x slower than native mb_string in my testing.

Larger offsets are still fairly efficient for Latin text, but can be up to 100x slower than native if the text is heavily multibyte and we have to slog through a few hundred kb.

Parameters:

string	$str
int	$start
string	$count

Returns:

string

static Fallback::mb_substr_split_unicode	(	$	str,
		$	splitPos
	)		[static]

Parameters:

string	$str
int	$splitPos

Returns:

int
