It probably would be useful to have a global way (a toggle switch)
of treating OCTET STRINGS as ascii text.

What I did was change rfc1759 so the OCTET STRING field I wanted to read
was DisplayString in the mib we used...

I've seen behavior in some other managers which I really don't
understand (I think its doing scanning of the strings...if all bytes
pass isprint() and it ends in a NULL, it treats it as an ascii string,
Otherwise its displays hex bytes...

I understand DisplayString is
deprecated, and Utf8String should be used in future mibs...
