mrxvt-devel does not show non-ascii character before end of line

[José García Juanino]

Hello,

after upgrade from 9.2 to 10.0 and rebuild the ports, mrxvt multi tab
terminal shows a strange issue: when you type an non-ascii character, it is
hidden from terminal unless you type another new character just behind.
Indeed, the exact bug is that mrxvt will not show any non-ascii character
before end of line. To reproduce this issue, you can type the following in
mrxt terminal, built from ports with the default options:

$ echo "añ"  > myfile
$ cat myfile
a
### ñ is not shown

(substitute spanish ñ by any other non-ascii character and you will get the
same issue).

mrxvt is rather ancient and not mantained by upstream, but actually is the
best multi tab terminal. But with this annoyed bug, I think it should be
definitively deprecated. Any idea to fix this bug, or some proposal on a
good multi tab terminal? (ignoring  kde or gnome related terminals, as they
need huge and complex dependencies).

Regards
