3940 - Unicode Conversion- ISO-2022-JP page does not display hankaku katakana characters

Status: VERIFIED FIXED

(Core :: Internationalization, defect, P2)

Description

[Teruko Kobayashi]

Tested 3-17-99 Win32 build.

The page contains Kanji and hankaku katakana.  After the double-byte characters are displayed, the page does not
display anything.  The part of hankaku katakana is the point the page does not display anything.

I put the simple test case in http://babel/tests/browser/bft/jis/aiu-jis.html which contains only hankaku katakana.
It does not display anything even though I click on Reload button.

It is ESC ( I 123 ESC ( B
erik: what is ESC (  I ?
I don't think hankaku is part of ISO-2022-JP. We should think carefully about
the error handling of our converter. Should accept ESC ( I ? ( in my opinion, we
may not want to but 4.x did. We  may be foreced to do it for backward
compatability) or we should at least make sure it convert correctly after the
ESC ( B.

Erik, please help to give us opinion.

The iso-2022-jp escape sequences are as follows:

  ESC(B   ASCII
  ESC(J   JIS X 0201-1976 Roman
  ESC$@   JIS X 0208-1978
  ESC$B   JIS X 0208-1983

The following escape sequences are not part of iso-2022-jp:

  ESC(I   JIS X 0201-1976 Kana
  ESC$(D  JIS X 0212-1990

However, our old code base accepted these escape sequences. Also, in networking
it is better to be liberal in what you accept, and conservative in what you
send out. So we should accept these escape sequences at least for receiving,
and we may even need to use one or both of them for sending to remain compatible
with our old code base.

Naoki may have further input on the Hankaku Kana issue for mail/news.
