SwiftKey inserts unexpected unicode 8203 character
I am using SwiftKey Beta keyboard (Android) V6.7.2.14
I found that it inserts unicode 8203 character (Unicode Character 'ZERO WIDTH SPACE' (U+200B)) between word in Thai language
If I type "ลมปราณภูตอุดร", I will get "ลมปราณ​ภูต​อุดร" (in HTML escape format).
The text displays correctly but the problems are
1. If I use it as game id, my id cannot be found by my friends when they search for it but type it with different keyboard (not SwiftKey)
2. Some app doesn't accept that character, and return error. I found this problem in some Thai bank apps.
