Spare language
Hi all,
please, could you help me with language support in API. I am using short language code like this:

https://api.themoviedb.org/3/movie/634?language=cs  

But in my language, there is missing some descriptions and videos.
I wanted to add english language as a spare language.
It seems that it is working only in long format like this:

https://api.themoviedb.org/3/movie/634?language=cs-CZ%2Cen-US

but not like this

https://api.themoviedb.org/3/movie/634?language=cs%2Cen  

Please, could you help me, why there is not working short form of language code?
And description is still missing.
Thank you very much.

A spare language in the API Request is not yet possible.
Fallback feature is in the plans.
It will be one of the next to be implemented.

Furthermore, I suggest using the language specification using the language-COUNTRY format.
All information is stored considering language-COUNTRY.
It seems to work much better.
I believe that as there are languages spoken in more than one country, the system works better.
And maybe in the future it will only work like this.

For example:
A Language with Multiple Countries

ar  Arabic 2 (AE+SA)
de  German 3 (AT+CH+DE)
fr  French 2 (CA+CH+FR) only CA and FR
ms  Malay 2 (MY+SG)
zh  Mandarin 3 (CN+HK+TW)
pt  Portuguese 2 (BR+PT)
es  Spanish 2 (ES+MX)
