What steps will reproduce the problem?

in !BAT file with UTF-8 encoding

set /u /p:4 ask= 暂存 XP ISO 到内存吗？如果从 USB-HDD

What is the expected output? What do you see instead?
should prompt but get
<
Report bug! lpos=0, start=-14, len=97, llen=0, plen=106, section=1


if line is shortened then it works OK - so is line length issue.


What version of the product are you using? On what operating system?
0.4.5c 2104

max length = 97  - but if UTF-8 used then max length is only 49 because each 
glyph is 2 bytes.

Can length be increased?
