These are just the Win95 TrueType Character sets, which obviously appear when you run an Office app under Win95.
The 0 to 127 codes are identical to their couinterparts in the IBM PC-8 set (also called the ASCII or lower ASCII set).
The characters above 127 are Win specific and the addition of the leading 0 (eg 0128) allows backwards compatibility.
Font designers are supposed to use the standard set. This is, unfortunately, limited to 224 characters by the possible 8-bit combinations, minus the 32 nonprinting "control" characters. Any font designer wishing to add specialised characters (scientific, wingdings etc) must drop standard characters to put them in their place.
The forum obviously uses a different font to you (highly unlikely to be Win95!! (Sun Solaris/Star??) so the codes can produce different characters.
