Issues with Vietnamese and SMS

Hello,

I had submitted a bug report / support request and I'm not seeing any resolution to it.
My issue is this....

When I compose an SMS message in Vietnamese and send it via the stock Google Messeges app, all of the accents are removed and the text becomes unreadable.
In Vietnamese, accenting on letters are critical to understand what's being said. Without them, you can't even understand what's written by using context.

Also, when I type in an ellipsis (...), Swiftkey freezes, then gives an error report. After the error report, it takes you back to the message window and it adds a second ellipsis. If you try to backspace to delete the ellipsis, Swiftkey throws another error and returns to the message with an additional ellipsis:

Example:

Open message and type in text with an ellipsis... [crash report here]

return to message

Open message and type in text with an ellipsis...... [backspace to delete ellipsis >> crash again]

return to message screen

Open message and type in text with an ellipsis.........

it keeps adding another ellipsis and you can't remove them.

I have uninstalled and reinstalled...has not fixed the issue.

My phone is a Note Edge on Verizon
My android version is 6.0.1
My swiftkey version is 6.5.8.26

Thanks,
Faith
