en-GB_GB --> en_GB

and there is at least one tag with a three letter language tag (ISO 639-2)::
|
||||
|
||||
fil_PH --> fil_PH
|
||||
|
||||
The locale code ``no_NO`` from Startpage does not exists and is mapped to
|

``nb-NO``::

|

babel.core.UnknownLocaleError: unknown locale 'no_NO'
|
||||
|
||||
For reference see languages-subtag at iana; ``no`` is the macrolanguage [1]_ and
|
||||
W3C recommends subtag over macrolanguage [2]_.

Use macrolanguages with care. Some language subtags have a Scope field set to

macrolanguage, i.e. this primary language subtag encompasses a number of more

specific primary language subtags in the registry. ... As we recommended for

the collection subtags mentioned above, in most cases you should try to use

the more specific subtags ... `W3: The primary language subtag

===================

The displayed name in Startpage's settings page depend on the location of the IP

when the 'Accept-Language' HTTP header is unset (in the language update script
|

we use "en-US,en;q=0.5" to get uniform names independent from the IP).

Each option has a displayed name and a value, either of which may represent the

language name in the native script, the language name in English, an English
|
||||
transliteration of the native name, the English name of the writing script used
|
||||
by the language, or occasionally something else entirely.
