Probably most readers here don't have an ï¿½-key on their keybord. So
here is another example:

IDL> print,!version
{ x86 Win32 Windows Microsoft Windows 7.0 Oct 25 2007 32 64}
IDL> mu='ï¿½' ; (the greek letter)
IDL> help,mu
MU STRING = 'ï¿½'
IDL> help,byte(mu)
<Expression> BYTE = Array[2]
IDL> print,byte(mu)
194 181

The string entered in the workbench command line is encoded in UTF8.
Using this string as a title in direct graphics results in a mu
preceded by an "A" with a hat. Direct graphics don't like UTF8. It
would need string(181b) for a mu.

If I don't miss something, Reimar is asking for a function to convert
the UTF8 string to ISO8859(?).
