non-ASCII characters, is there a reason?

Question
I would like to create keys which contains Thai letters (ex: "ป็นไรครับ").
Unfortunately, I'm facing the error of non-ascii characters.
Right now, my keys are stored in Firebase and I wanted to sync with Hive.
Is there a technical reason why we couldn't do something like that?
Thanks

Code sample

openBox.put("ป็นไรครับ", 10);

Version

• Platform: Mac; ios ; android
• Flutter version: 1.9.4+hotfix.4
• Hive version: 1.0

Yes there is. Keys have to be read very quickly. It is super fast to read ASCII strings compared to Unicode strings...

Ok.
I'll write that content as a value then :)

Thanks
