1.Open a blank Writer document.
2.Switch keyboard to Thai.
3.Type text “มิถุ” by press “,b5”.
4.The function autocomplete will display the full word.

@fme: I suggest to autocomplete only at cell boundaries. Splitting cells into different portions is not

I find more test cases for this bug

A) switching font style inside a cluster
Step to reproduce :-
1.Open Writer
2.Switch keyboard to Thai
3.Type the character “ก” (by pressing “d”)
4.Then change font style, e.g. Bold or Italic
5.Type the character “ ิ” (by pressing “b”)

B) add a non-base character in record change mode
Step to reproduce :-
1.Open Writer
2.Type some word in Thai
3.Choose Edit > Changes > Record
4.Type the character “ ่” (by pressing “j”)

This problem occurs when some text is splitted into 2 runs. if a non-spacing
vowel mark (e.g. ุ) is placed at the first character of the second run, the text
will be displayed overlap. But the problem will occur in the first (regarding
position in the document) autocompleted word in a document. I've pasted 2
snipplets of content.xml to show examples:-

A: Western autocomplete case:
<text:p text:style-name="Standard">January</text:p><text:p

B1: Thai autocomplete case with overlapped text:
<text:p text:style-name="Standard">มิถ<text:span text:style-name="T1">
ุนายน</text:span></text:p><text:p text:style-name="Standard"><text:span

B2: Thai autocomplete case without problem:
<text:p text:style-name="Standard">กรก<text:span text:style-name="T1">
ฎาคม</text:span></text:p><text:p text:style-name="Standard"><text:span

You will see that, in case B1 and B2, the first autocompleted word (e.g.
"มิถุนายน") is splitted before the vowel mark (ุ). But in the second autocompleted
word (e.g. "มิถุนายน"), the entire autocompleted word is placed in the text:span
element. OOo seems not to be able to display non-spacing mark at the begining of
a text run so that's why the text is displayed overlapped.

Note that the splitted autocompleted word always happend if you insert the word
before any other autocompleted word. That is, it happend only for the first
occurance of such autocompleted words.

My questions are:
1) the text:style-name="T1" is used in Thai (or every CTL?) autocomplete case
but not in Western case. What's it for?
2) I guess the <text:span text:style-name="T1"> element should actually span the
whole autocompleted word like this <text:span text:style-name="T1">
มิถุนายน</text:span>, right?
