Comment 0 for bug 1372425

I'm not fluent in English but I'll try my best to describe.

I'm using Xubuntu 14.04, and recently came upon this issue using text editors in xterm. Sometimes the the width of Chinese full-width comma '，' is not correctly displayed(shortened), resulting in charaters 'overlapping'.

See the 'overlapping' effect at:

See the shortened full width comma at:

Note that the first line shows 'shortened' full-width comma, second and third line show the normal full-width comma.

----------------------------------------------------------
Step to reproduce in Xubuntu 14.04:

1. Make sure you have these packages installed:
     'xterm', 'nano', 'fonts-wqy-zenhei';

2. Create/modify ~/.Xresources with the following contents:

! ========= start of .Xresources ========= !
!mouse selecting to copy, ctrl-v to paste
XTerm*VT100.Translations: #override \
Ctrl <KeyPress> V: insert-selection(CLIPBOARD,PRIMARY,CUT_BUFFER0) \n\
<BtnUp>: select-end(CLIPBOARD,PRIMARY,CUT_BUFFER0) \n\

XTerm*utf8Title:true
XTerm*cjkWidth:false
XTerm*faceName:Dejavu Sans Mono:pixelsize=12
XTerm*faceNameDoublesize:WenQuanYi Zen Hei Mono:pixelsize=13
! ========= end of .Xresources ========= !

3. execute in bash: xrdb -merge ~/.Xresources

4. Start nano in xterm;

5. copy the following string(not including quotation mark):
     '您好，几位？'

6. In nano, press Ctrl-v to paste.( Previously configured in ~/.Xresources )

7. Press back arrow key 1~3 times to see the effect.

Seems that only pasting those characters messes up the display, typing them in has no effect.
