I thought such indication was too technical for average lynx user
and not very useful in fact (say, I run into japanese text
with any european display charset).  Instead, this can be indicated
from Info Page: [7bit chars only] / [7bit approximation was used]
/ [few not recognized characters filtered out]  or so.

I have a little experience with "utf-8" pages
but seems documents in normal "8bit charsets" feel good without this mode.

I grep the code for LYRawMode and found only a couple of matches
for unrelated things in GridText.c

Please give examples.
You mean to overload "Raw Mode" key for `visualizing' (few)
unrecoverable characters while the usual meaning of that key is another...
