When a text is processed via Postscript, some characters have a special
meaning:
` : go to greek
' : go to special
~ : go to ZapfDingbats
? : go to subscript
^ : go to superscript
! : go to normal level of script
& : backspace one character
# : end of greek or of ZapfDingbats
Note1: This special characters have no effect on the screen.
Note2: To print one of the characters above in the Postscript file
use the escape character "@" in front of the character.
If you do not produce Postscript, you can use the characters directly.
If you want Postscript, you must use the "@" character in front.
Since we introduced the TLatex class, this algorithm is becoming
obsolete.
We keep it for back compatibility. However we strongly encourage our
users
to move to the TLatex convention. We could introduce a switch to ignore
the old convention.

This should be automatic. Give me an example where this does not work.

Again, this should work. Could you give me an example when it does not
work?
