Jackie, I assume you mean http://www.ramsch.org/martin/uni/fmi-hp/iso8859-1.html

You can do the same with both sites, just copy and paste, so if you want a ˛, copy either the ˛ or "& # 1 7 8" - ² but some people prefer to use alt-number instead.

The bit about MC˛ was that I tried to write it in Microsoft Word (using the superscript option) then copy and paste it in but it didn't work.
