TRN and ELM display issues

[Trilateral]

Both ELM and TRN get into a weird xterm display mode sometimes where "clear"
doesn't work and so the screen output gets screwed up. This is on Solaris 2.8
and as far as I can tell, the only overlap between the two programs is in
the CURSES and TERMCAP library usage. I checked for new sun patches but no joy.

What appears to be happening is that when a Subject is listed which has weird
characters in it, it fries the term seting. As an example from TRN

Subject: Re: USBF Trials - Congratulations to the Cohen Team USA II
0000000 123 165 142 152 145 143 164 072 040 122 145 072 040 125 123 102
S u b j e c t : R e : U S B
0000020 106 040 124 162 151 141 154 163 040 055 040 103 157 156 147 162
F T r i a l s - C o n g r
0000040 141 164 165 154 141 164 151 157 156 163 040 164 157 040 164 150
a t u l a t i o n s t o t h
0000060 145 040 103 157 150 145 156 040 124 145 141 155 040 226 040 125
e C o h e n T e a m 226 U
0000100 123 101 040 111 111 012
S A I I \n

In this case the octal 226.


As anyone else observed this effect. Thanx.

A vt220 treats that as a control character (start guarded area).
It's trn's job to convert it into a printable character if your locale
is set properly.

(There are some Russian character sets which may use this, which would require
more work to set up, but this article doesn't appear to fall into that
category).
