How to keep uppercase when passing parameters from url into whatsapp api web?

Question

I have a problem here. Here is my sample code: https://api.whatsapp.com/send?phone=[International Ph. Number]&text=GoodMorning!

Copy the following codes and insert into any browser and change the [International Ph. Number] to any international phone number. What's the problem here is when showing in the api.whatsapp.com, they were fine but when passing into https://web.whatsapp.com/ all my uppercase turned into lowercase! I even tried url encoding such as the % still doesn't work for me.

It's fixed internally by WhatsApp, update will be pushed out soon (see thread: https://whatsappen.com/whatsapp-click-to-chat)

EDIT 12/08/2017: it's fixed since a couple of days. Try: https://api.whatsapp.com/send?phone=&text=SomeCapitalLetters
