/* File strings/ctype-czech.c for MySQL.

	This file implements the Czech sorting for the MySQL database
	server (www.mysql.com). Due to some complicated rules the
	Czech language has for sorting strings, a more complex
	solution was needed than the one-to-one conversion table. To
	note a few, here is an example of a Czech sorting sequence:

		co < hlaska < hl<EFBFBD>ska < hlava < chlapec < krtek

	It because some of the rules are: double char 'ch' is sorted
	between 'h' and 'i'. Accented character '<EFBFBD>' (a with acute) is
	sorted after 'a' and before 'b', but only if the word is
	otherwise the same. However, because 's' is sorted before 'v'
	in hlava, the accentness of '<EFBFBD>' is overridden. There are many
	more rules.

	This file defines functions my_strxfrm and my_strcoll for
	C-like zero terminated strings and my_strnxfrm and my_strnncoll
	for strings where the length comes as an parameter. Also
	defined here you will find function my_like_range that returns
	index range strings for LIKE expression and the
	MY_STRXFRM_MULTIPLY set to value 4 -- this is the ratio the
	strings grows during my_strxfrm. The algorithm has four
	passes, that's why we need four times more space for expanded
	string.

	This file also contains the ISO-Latin-2 definitions of
	characters.

	Unformal description of the algorithm:

	We walk the string left to right.

	The end of the string is either passed as parameter, or is
	*p == 0. This is hidden in the IS_END macro.

	In the first two passes, we compare word by word. So we make
	first and second pass on the first word, first and second pass
	on the second word, etc. If we come to the end of the string
	during the first pass, we need to jump to the last word of the
	second pass.

	End of pass is marked with value 1 on the output.

	For each character, we read it's value from the table.

	If the value is ignore (0), we go straight to the next character.

	If the value is space/end of word (2) and we are in the first
	or second pass, we skip all characters having value 0 -- 2 and
	switch the passwd.

	If it's the compose character (255), we check if the double
	exists behind it, find its value.

	We append 0 to the end.

** Calculate min_str and max_str that ranges a LIKE string.
** Arguments:
** ptr		Pointer to LIKE string.
** ptr_length	Length of LIKE string.
** escape	Escape character in LIKE.  (Normally '\').
**		All escape characters should be removed from min_str and max_str
** res_length   Length of min_str and max_str.
** min_str      Smallest case sensitive string that ranges LIKE.
**		Should be space padded to res_length.
** max_str	Largest case sensitive string that ranges LIKE.
**		Normally padded with the biggest character sort value.
**
** The function should return 0 if ok and 1 if the LIKE string can't be
** optimized !
