Description Masaki Katakai 2006-04-03 02:55:05 UTC 
If multibyte characters (double-width character e.g. Japanese) are in line of
editor,
tab position is not correct.

a<tab>|
<A><tab>|

<A> is a japanese character. The next tab position (|) should be the same in
above case, but it's different.

Tab is a basic functionality so I filed this as P2.

We will need to change the way how we compute the tab position. Currently the
tab position is set by the number of characters - each 8th character is a TAB
position. We will need to change it to align either to a graphical position or
we will have to know that a particular Unicode char spans two regular chars.
Anyway it seems that this will require broad changes.

Waiver request: This problem affects all users writing text in asian locales in Netbeans editor. The problem is not
fatal, it is possible to enter text, but navigation in the text can be confusing and hard. At the moment a solution for
this problem is unknown and attempting to fix the problem would require some research and experimenting. We have no time
estimate for the complexity of the fix.

Planned for 6.1?
Comment 5 Jan Becicka 2008-06-09 12:41:11 UTC 
Lowering to P3. We have only single report mentioning this issue.
Comment 6 Miloslav Metelka 2008-11-14 08:38:17 UTC 
This requires broad changes in the view hierarchy and other parts. Marking for later.
