42574 - Full-width space in JPN cannot be input at the beginning of a line

Status: VERIFIED FIXED

(Core :: DOM: Editor, defect, P3)

Description

[Katsuhiko Momoi]

** observed with 6/13/2000 Win32 build **

This problem was first observed in a mail composer window
by a Japanese user but the same problem occurs with HTML editor.

When you want to input a full-width (Zenkaku) space in Japanese 
on a new composer document at the beginning of a line, you cannot
do this at all no matter how many times you press the Space.

If you first enter some characters, then you can backtrack and
enter a full-wodth space. Apparently some people do this quite often
in Japanese and it is a very annoying problem.

interesting.  I dont have this problem on the mac.  It must be windows only.  
This may mean that it is a problem with layout (particularly the win text 
rendering code).  I'll try to get a recent windows build together and check it 
out.

Yes. That seems to be true with Kotoeri. 
Kotoeri does not offer the option to choose
between half-width and full-width spaces in
Japanese. Under Windows IME from MS, there is 
such an option and the problem happens when
the full-width space option is chosen.

I have a different Mac Japanese IME (ATO12) and
there if I turn on half-width option, Mac has
a problem with inputting that without hitting
the space bar twice.

Sujay, the origanal bug is not fixed, yet.  Did you test 10/31 build to test this?
This bug should not be verified until the bug 47015 is fixed.

nominating for nsbeta1 since there might be a fix for it.

Checked it on 05-21 Win32 trunk:
NT-Ja: still has this problem.  Enable IME-Ja, when try to input a full-width 
space at the beginning of a new line by press "space", the cursor will become a 
very small mark and it will positon at the beginning of line.  This exists in 
both Mail and Composer.
However, it not reproducible on WinME-Ja and Win98-Ja.

Comment 21

[Joe Francis]

Yuying: can you repeat the test across the different wondows os's and add in
this step:  in the debug menu (use a debug build), choose "Dump Content Tree"
after typing the full-width space.  You will get data in the console window
which represents the content tree for the document.  If you could report back
what that data is, and if it is different on NT-Ja vs. WinME-Ja and Win98-Ja,
that might be very helpful.

[Teruko Kobayashi]

This is no longer reproduciabe in Winnt 4.0J, either.  I found the 
half-width problem - bug 83515.

Verified as fixed.
