Bug#1123877: xterm: display issue with the U+0FE0 character
Package: xterm
Version: 406-1
Severity: normal
I've found this issue after an error in copy-pasting...
Note: For the test with the triple-click, make sure that
"a" and ">" are in different character classes.
qaa% printf '<a\u0FE0>\n'
<a>
which appears as "<a>" (3 ASCII characters) in xterm. Then
triple-click over the "a" character. This gives "<a>>" in
reverse video, i.e. the last character is repeated.
And slowly moving a window over the xterm one from left to right
transforms the "<a>" into "<a >" (with a space between the "a" and
the ">").
This U+0FE0 does not exist in the Unicode database here, but in any
case, it should be handled in a consistent way.
