[sword-devel] support for locale codes with region/script subtags

[DM Smith]

Didn't mean this to become a JSword thread. We're using Java 5 which does not have any notion of script. So we roll our own and replace it when we get to Java 7.

The question still remains, is _ intended in the module conf? If so, we'll change JSword code to handle it.

Their language codes (as of the 1.2.1 release just made, which corrected the code for the Devanagari version) are: ur (Urdu in Arabic script--the usual script for Urdu) and ur-Deva (Urdu in Devanagari script).
