Naohisa Murakami 1426601cf7 Use index of the supported tags to choose user lang (#15452) ... Fix #14793. The previous implementation used the first return value of matcher.Match, which is the chosen language tag but may contain extensions such as de-DE-u-rg-chzzzz. As mentioned in the documentation of language package, matcher.Match also returns the index of the supported tags, so I think it is better to use it rather than manipulate the returned language tag.		2021-04-14 19:52:01 +01:00
