/* 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 < hláska < hlava < chlapec < krtek

        It because some of the rules are: double char 'ch' is sorted
        between 'h' and 'i'. Accented character 'á' (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 'á' 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.
