In this encoding, ASCII characters 9 (tab), 10 (nl), 13 (cr), 32 through
37, inclusive, 39 through 91, and 93 through 127, inclusive, are
unchanged.
Is it really safe to allow delete (127) to pass through unchanged?
Doesn't it have a special meaning on some systems (like deleting the
previous character)?
Also, why don't you allow Control-L to pass through? (You even use it
yourself e.g. in your text version of the RFC-XXXX draft.)
Style #2: An 8 bit value from 160 through 255 may, alternately, be
represented by an ampersand character followed by the character
obtained by the removal of the high order bit, i.e. by subtracting
128 from the value. Thus the 8 bit value 193 may be represented as
"&A".
I think this should be 161 to 254. 160 - 128 is 32 (space), which may
cause problems if it is at the end of a line, since some systems strip
trailing spaces, as you say somewhere else in the draft. Also, 255 -
128 is 127 (delete), which is dangerous as I explained above.
