[Mlterm-dev-en] cut&paste Big5 and UCS - Big5 convertion.

[Araki K. <j00...@ip...>]

        Hi,

        I fixed Big5 copy and paste problem.
        Please checkout current CVS repository and test it.

--- commit log
[20011210]
* Big5 copy and paste problem is fixed.
  (--big5bug option is added)
* minor bugs of bidi are fixed.
* documents are updated except --big5bug option.
* character shaping stops unless mlterm works on bidi mode.

        BTW I found XmbTextListToTextProperty() generates strange CTEXT
        sequence when TextList contains Big5.
        I asked it to Kubota Tomohiro san , and he pointed to me XFree86
        ChangeLog below.

        XFree86 4.1.0 or before all have these bugs.
        
        Even if these bugs exist , applications which use XmbTextListToTextProperty()
        can communicate with each other in Big5 , but the problem is that mlterm
        doesn't use Xlib i18n functions.
        
        I don't know which way is preferable , but at the present time I avoid this
        problem by adding a new option.
        if your XFree86 is buggy , start mlterm as follows

        $ mlterm --big5bug

        or add
        
        big5_buggy = true

        in ~/.mlterm/main , and you can copy and paste Big5 characters on buggy XFree86.


        In addition , mlterm has another Big5 problem.
        mlterm now uses BIG5.TXT which was in http://www.unicode.org/Public/MAPPINGS/EASTASIA/OTHER/
        (and obsoleted) to convert between BIG5 and UCS.

        But according to Sakamoto Hironori san ,

        ftp://xcin.linux.org.tw/pub/xcin/i18n/charset/BIG5.gz

        should be used as a convertion table , so I will do so.

        
        Are there any problems ?
        I would like native speakers' comments about these.

        Best Regards.
