tokenize_and_fold

Description:

[ CCode ( array_length = false , array_null_terminated = true , cname = "g_str_tokenize_and_fold" ) ]
[ Version ( since = "2.40" ) ]
public string[] tokenize_and_fold (string transit_locale, out string[] ascii_alternates)

Tokenises 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 isalnum or 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:

ascii_alternates	a return location for ASCII alternates
string	a string
translit_locale	the language code (like 'de' or 'en_GB') from which `string` originates

Returns:

the folded tokens
