bug report about addstr with cjk characters

[WANG WenRui]

Hi,

  I found this problem when I was reading a letter from a traditional
  Chinese user with mutt, which is built with ncursesw 5.4. Most
  traditional Chinese characters is unreadable. At last I am sure that
  the problem comes with perhaps a bug in ncurses. 

  My locale is GBK, under which the characters of Traditional Chinese
  is coded between 128 - 160, so, when "addstr" a string of them, they
  are "unctrl"ed in waddch_nosync (base/lib_addch.c) in the first
  place. This behaviour is not expected.

  To see if my idea is right, I removed the 128-160 part of unctrl
  table(by comment out 2 lines in MKunctrl.awk), then rebuild the
  ncurses library. After that, traditional Chinese characters are well
  displayed. The two screenshots are in the attachment.

  So how can this be fixed? Thanks in advance.

Regards
wwr
