See String#tr in ruby.
Function signature will be func Translate(str, from, to string) string. In this function, from and to are a pattern defined as following.
- Special characters:
- means a range of runes, e.g. "a-z" means all characters from 'a' to 'z' inclusive.^ as first character means a set of all runes excepted listed, e.g. "^a-z" means all characters except 'a' to 'z' inclusive.\ escapes special characters.
- Normal character represents itself, e.g.
"abc" is a set including 'a', 'b' and 'c'.
Translate will try to find a 1:1 mapping from from to to. If to is smaller than from, last rune in to will be used to map "out of range" characters.
There should be a set of functions to "compile" translate from and to string to a rune set for better performance.
