locales are limited to TwoLetterISOLanguageName

[joaomatossilva]

on NumberToWordsExtension class:

if (ConverterFactories.TryGetValue(CultureInfo.CurrentUICulture.TwoLetterISOLanguageName, out converterFactory))

this sentence is limiting the locale awareness of the library. There is room here for improvement. It could be implemented the same way resource files are located.
xx-XX first if there is a match, xx next, and default for last.

Good point. Wanna send me a PR for that? :)

I also would really like to see some failing tests with the current implementation. The pt-BR and pt-PT case you've commented on comes to mind.

I'll look into this when I get home tonight.

This is now fixed in #194

Thanks @akamud for pointing this out. FWIW if you put fixes #168 in your PR description merging that would close this issue automatically too.

[akamud]

Oh, didn't know about that. Thanks for the info! :)

[MehdiK]

No worries. More info here and here.
