Dave,
There are some letters in foreign languages that do not occur in English.
Even citation marks or special symbols like question mark etc often are not
transferred in the internet or via e-mail the same way as they were stroke
on the keyboard. To name just a few languages which have letters not used in
English: French, Swedish, Norwegian, Danish, Icelandic, German, Finnish.
Then there is of course the greek letter used for micro - this would be the
only possibility in my opinion, because all other abbreviations like pico,
milli, mega, giga etc. should transfer correctly. Sorry, I do not have the
possibility to check ASCII 145 and 146. In case you cannot get a direct
explanation from radsafer I would recommend to contact the sender of the
message.
