Kendo cultures files are generated base on the Window 7's culture information. Some of the culture information could be outdated, like in the case with pt-PT, pt-BR, es-ES, es-CO, es-CL
files, and we will update them. The updated files will be available in the next internal build of Kendo UI. For your convenience I have attached the updated culture scripts to this message. Just replace the files in the cultures folder.
With regards to your other question related to the zh-TW, ko-KR, ja-JS, fr-CA
cultures, calendar header uses culture format to render the Month-Year information and that is why the order of "MM" and "YYYY" specifiers is not culture specific, because there is no sufficient information about Month-Year positioning. I prepared a Kendo Scratchpad demo
, which shows how to implement culture header format. Check it and let me know if something is not clear.
