Top Forums Shell Programming and Scripting Perl script backspace not working for Unicode characters Post 302500855 by tdw on Tuesday 1st of March 2011 07:30:50 PM

Thank you very much for the pointers. I followed tips from 2nd link and added the line in my script:

system('stty iutf8');

It worked but not completely. Normal width characters worked fine, like אזחט. But wide characters like Chinese, one BACKSPACE erased all bytes correctly (3 bytes per char), but cursor moved back only one term cell instead of two cells for wide chars. The result was that some Chinese characters were still left visible on terminal even after all of the underlying bytes were deleted.
