The second character in the two right words counts two, because when I  
start to press <RIGHT> I have to press it twice on this character to  
reach the third one, and from this it takes one <LEFT> to reach the  
second character and two <LEFT> to leave it, reaching the word  
beginning. At the end of the visible characters the cursor jumps to a  
completely unexpected position: early in the session it was the end of  
the Braille "Hello" (with column-number-mode enabled I still saw line  
#44 and column #48) greeting, which later became visibly one line  
above (line ending character of the Bengali greeting) while mode-line  
still showed (44,48). <UP> and <DOWN> put the text cursor on the Khmer  
or the Malayalam line endings. C-e somewhere in the Lao greetings puts  
the cursor to Bengali or Braille line ends – and C-a there puts the  
cursor on column #0 of line #44, i.e., the L of Lao.

When I click on the last but one character of the Lao greetings (44,  
46) the second Thai greeting changes its shape... (normal first,  
clicked last)
