Browser language strings are - versus _

[digitalrinaldo]

I was just wondering is there is an option for mapping en_US to en-US the browsers ask for locales using a "-" instead of an "_" and thanks for the useful library.

+1. I'd actually love any insight/clarity into when to choose - vs. _.

The - format used in HTTP is defined in RFC 2616 Section 3.10 and the _ format is used on Posix (linux, unix, OSX) though I'm currently unable to find the spec that defines it.

Locale objects currently have fields:

• code: as-is string of the locale, as received
• normalized: language lower case, underscore, country upper case, es: en_US

wouldn't it be enough to add a browserized param with language lower case, dash, country lower case? (es. en-us)
