`gawk` bug in conflict with `pt-PT`, while only `pt-BR` works, even if with a set translation engine

[gusbemacbe]

Hello!

If you add only one language, it will work:

$ trans -b :pt-BR "File and folder"
Arquivo e pasta

But if you use pt-PT, it will fail with a gawk bug:

$ trans -b :pt-PT "File and folder"
gawk: /dev/fd/63:215: fatal: internal error: file interpret.h, line 254: unexpected parameter type Node_val

With a set translation engine, any language will fail with gawk bug:

$ trans -engine bing :pt-BR "File and folder"
gawk: /dev/fd/63:215: fatal: internal error: file interpret.h, line 254: unexpected parameter type Node_val

$ trans -engine bing :pt-PT "File and folder"
gawk: /dev/fd/63:215: fatal: internal error: file interpret.h, line 254: unexpected parameter type Node_val

I solved with the #463, but I will comment on #432.

From what I know, Google Translate ONLY has one Portuguese and that only outputs Portuguese spoken in Brazil. I never seen it outputing Portuguese spoken in Portugal. I already nagging the Google Translate team if I need to wait 200 years for them to add support to Portuguese-Portugal and correct the language list. Bing does have both languages separated but the Portuguese-Portugal has leftovers from Portuguese-Brazil. No idea why they flavour a derived language instead of the NATIVE language. 
This obviously will never work because Google Translate does not have support for pt-PT: 
┌──(pi㉿raspberrypi)-[~]
└─$ trans -b :pt-PT "File and folder"
Arquivo e pasta
------> If it worked, it would output "Ficheiro e pasta".

This also does not work:
┌──(pi㉿raspberrypi)-[~]
└─$ trans -engine bing en:pt-PT "File and folder"
File and folder
[ English -> Português ]

┌──(pi㉿raspberrypi)-[~]
└─$ trans -engine bing en:pt-BR "File and folder"
File and folder
[ English -> Português ]
