Yes, that's a potential cause. Now I can reproduce it on gnome-terminal
and uxterm using this command:

LANG=th_TH.UTF-8 whiptail --title "ทดสอบวรรณยุกต์" \
  --msgbox "วรรณยุกต์อยู่ท้ายบรรทัดได้หรือไม่" 8 24

(The LANG setting is just to ensure UTF-8 locale. You can test it on, say,
en_US.UTF-8 locale as well.)

You can see the combining character is missing in the first line.
And the OK button is randomly distorted on different calls.

So, now I think it's newt's problem. I'll file a bug soon.
