New language request for Min Bei Chinese (mnp).

It should be "Hani".

With the native name you give (in Latin and Han), this Han name "閩北語" uses Traditional Chinese (Hant). For Simplified Chinese (Hans) it should be "闽北語"

So do you intend to use Latin or Hant as the default option for "mnp", or do you want to translate to "mnp-Latn" and "mnp-Hant" separately?

And how the conversion from Hant to Hans will be done (using the converter already used for Mandarin Chinese?)

Note that actual translations of messages should not be dual script (they should only fallback from one version to the other, possibly with the transliterator, or to another Chinese language with the same script variant.

You need to specify how each variant will fallback (to another variant or to another language)

Note that the Portal:Mnp page is already created. Check that names for variants are accurately identified.
