Subject: dialog: Text incorrectly wrapped at combining character
Date: Sat, 20 Feb 2010 18:26:44 +0700
Package: dialog
Version: 1.1-20100119-1
Severity: normal

When Thai text is wrapped at the character with a following combining
character, the combining character gets wrapped instead of staying with the
base character at line end.

Test case:

LANG=en_US.UTF-8 dialog --title "ทดสอบวรรณยุกต์" \
 --msgbox "วรรณยุกต์อยู่ท้ายบรรทัดได้หรือไม่" 8 23

Expected result: a dialog like this:

  │ วรรณยุกต์อยู่ท้ายบรรทัดได้ │  
  │ หรือไม่               │  
  │                     │  
  │                     │  
  │     <  OK  >        │  

What actually happens:

  │ วรรณยุกต์อยู่ท้ายบรรทัดได │  
  │ ้หรือไม               │  
  │                     │  
  │                     │  
  │     <  OK  >        │  

Notice the missing combining character at the end of the first line, which
gets incorrectly wrapped to the second line.

Also notice the missing combining character at the end of the second line.
This always happens regardless of how the text is wrapped. The last combining
character of the line is always lost.
