站点设置的区域设置默认值 (`locale_default`)

I wonder why no defaults were defined for unicode_usernames.

It’s disabled by default for security reasons.

@gerhard

unicode usernames is disabled by default and we strongly advise you to configure the allowed unicode username characters setting before enabling it in order to prevent homograph username spoofing.

I guess we could enable it by default for all locales that have a locale override for allowed_unicode_username_characters.
