63 // conversion of legacy mappings one LangID can map to multiple ISO codes, and
64 // one ISO code combination can map to multiple LangIDs. For compatibility with
65 // already existing calls it can also be a sequence as follows:
66 
67 // LANGUAGE_ENGLISH,    "en", ""
68 // LANGUAGE_ENGLISH_US, "en", "US"
69 
70 // Here, in a convertIsoNamesToLanguage() call "en-US" is converted to
71 // LANGUAGE_ENGLISH_US and "en" is converted to LANGUAGE_ENGLISH. A call with
72 // "en-ZZ" (not in table) would result in LANGUAGE_ENGLISH because the first
73 // entry matching the language and not having a country is returned, regardless
74 // of whether being sorted before or after other entries of the same language
75 // with some country. To obtain a _locale_ (not language only) in the order
76 // given, convertLocaleToLanguageWithFallback() must be called.
77 
78 // If the sequence instead was
79 
80 // LANGUAGE_ENGLISH_US, "en", "US"
81 // LANGUAGE_ENGLISH,    "en", ""
82 
83 // in a convertIsoNamesToLanguage() call "en-US" is still converted to
84 // LANGUAGE_ENGLISH_US, but "en" is _also_ converted to LANGUAGE_ENGLISH_US
85 // because no country was passed and it is the first entry to match the
86 // language, see code. A call with "en-ZZ" (not in table) would still result in
