strTokenizeAndFold

fnstring[] strTokenizeAndFold(string string_, string translitLocale, out string[] asciiAlternates)

Tokenizes string and performs folding on each token.

A token is a non-empty sequence of alphanumeric characters in the source string, separated by non-alphanumeric characters. An "alphanumeric" character for this purpose is one that matches funcGLib.unichar_isalnum or funcGLib.unichar_ismark.

Each token is then (Unicode) normalised and case-folded. If ascii_alternates is non-NULL and some of the returned tokens contain non-ASCII characters, ASCII alternatives will be generated.

The number of ASCII alternatives that are generated and the method for doing so is unspecified, but translit_locale (if specified) may improve the transliteration if the language of the source string is known.

Parameters

`string_`	a string to tokenize
`translitLocale`	the language code (like 'de' or 'en_GB') from which string originates
`asciiAlternates`	a return location for ASCII alternates

Returns

the folded tokens
