A MultiMapper performs a list of mappings from one string to another. You could of course just use gsub to do this but when you are just mapping strings, this is much faster.
Note that MultiMapper is immutable.
mapping = { ['à','á','â','ã','ä','å','ā','ă'] => 'a', 'æ' => 'ae', ['ď','đ'] => 'd', ['ç','ć','č','ĉ','ċ'] => 'c', ['è','é','ê','ë','ē','ę','ě','ĕ','ė',] => 'e', ['ƒ'] => 'f', ['ĝ','ğ','ġ','ģ'] => 'g', ['ĥ','ħ'] => 'h', ['ì','ì','í','î','ï','ī','ĩ','ĭ'] => 'i', ['į','ı','ij','ĵ'] => 'j', ['ķ','ĸ'] => 'k', ['ł','ľ','ĺ','ļ','ŀ'] => 'l', ['ñ','ń','ň','ņ','ʼn','ŋ'] => 'n', ['ò','ó','ô','õ','ö','ø','ō','ő','ŏ','ŏ'] => 'o', ['œ'] => 'oek', ['ą'] => 'q', ['ŕ','ř','ŗ'] => 'r', ['ś','š','ş','ŝ','ș'] => 's', ['ť','ţ','ŧ','ț'] => 't', ['ù','ú','û','ü','ū','ů','ű','ŭ','ũ','ų'] => 'u', ['ŵ'] => 'w', ['ý','ÿ','ŷ'] => 'y', ['ž','ż','ź'] => 'z' mapper = MultiMapper.new(mapping) mapped_string = mapper.map(string)
Returns a new multi-mapper object and compiles it for optimization.
Note that MultiMapper is immutable.

Performs all the mappings on the string.
