Symbol sorting

Symbol sorting can contain some literal or literal intervals. To describe literal intervals the '-' symbol is used which is staying between the first and last symbol in an interval. Examples of different intervals of one symbol sorting are as follows: [1-5] - digits from 1 to 5, [a-f] - Latin letters from a to f, [a-fq-x] - Latin letters from a to f and from q to x, two ranges are in use in the last symbol sorting.

If some of symbols: a or g or 7 or 4 can be in the determined positions, than the symbol sorting will be as follows: [ag47].

It's possible to specify allowable literals in a symbol sorting. Specifying of literals can be combined with specifying intervals: [14a-kz] means that a symbol in a string can be similar with 1, 4, Latin letters from a to k and with z letter. Letters, digits, punctuation marks, mathematical signs can be a literal. For example, ',' (coma), '!' (exclamation point), '+' (plus). It's possible to use '-' (minus) symbol even if it used for interval specifying. If specify '-' between a and z, it will be interval, but if specify it after opened square bracket - it will be minus. For example, [-,a-z] means that symbol sorting contain minus, coma and Latin letters from a to z.

To specify symbol sorting containing all symbols except of the specified, e.g. all symbols except of a,b,c, use the special negation symbol: ^ (cover). It's required to specify: [^abc] - all symbols (not letters, but symbols) except of a,b,c Latin letters.
