In version 680, OOo is no longer able to break lines between adjacent Thai words
that do not have a separator character between them (this is the normal case in
Thai). In version 1.1, OOo was able to correctly do this. This is a very serious
regression that makes OOo not usable for Thai. This bug lead to the problem in
issue 32911. 

This can be observed in both Writer and Calc (for cells with 'wrap text
automatically'). It happens on both Windows and Linux.

Test case for Writer :-
In Writer, load the attached .odt file which contains a line with 16 copy of a
Thai word 'การ' and a space in the middle. The line is formatted as CTL=Thai.
การการการการการการการการ การการการการการการการการ
Writer breaks the line at the space character. Actually the line can be breaked
every 3 characters so the right place should be at the ninth character from the
right.

Test case for Calc:
In Calc, load the attached .ods file which has a cell with the text 'การการ การก
าร'. Calc breaks the line at the space character while the line can be breaked
at the third character from the right.

Though line breaking doesn't work, moving the cursor by words still works
correctly. You can try moving cursor using ctrl-left/right in Writer and the
cursor will move between Thai word boundaries correctly.
