Localization (i18n) Options

[Gerald via Digitalmars-d]

I have a GtkD application for Linux where I would like to support 
localization. The current options in D seem pretty limited with 
the most recent being i18n-d 
(https://github.com/JakobOvrum/i18n-d). My code is structured for 
GNU gettext but I could make the effort and convert it to the way 
i18n-d works if that's the best option. The only other issue I 
can see with it is that it doesn't support country-language 
variations and from past experience that's a pretty big deal 
(just ask any Brazilians!).

I'd prefer a GNU gettext implementation but I know that's not 
available since it has been listed as a GSOC project for a couple 
of years. I could roll my own GNU gettext implementation but that 
would be a significant effort taking away time from my project 
which I'd prefer to remain focused on.

Are there any other options out there that I might not be aware 
of?
