demos : enhanced text mode remains gets stuck on

[<tim...@en...>]

Hello (again) !

Ethan reported that the enhanced text mode remains on when you run "load
'all.dem' ".

As it seems to be considered as a problem, I propose to add "set
termoption noenhanced" at the end of the demo file 'enhancedtext.dem'.

Ethan said that it does not happen under the X11 terminal, but I can
assure you that it does, as there's simply no reason for the X11
terminal to disable enhanced mode after the demo, as there is no command
to do it in this demo file. However, it appears to draw all text on
normal mode, because the X11 terminal tests input strings to see if they
really contain magic characters in "{}^_@&~", and if it's the case,
draws them with the normal routine.

Do you agree to add "set termoption noenhanced" at the end of
"enhancedtext.dem" ?
If yes, can somebody do it ?

Thanks !

Regards,

No, sorry.  I have explained the problem badly.

The point is that even if the terminal is in enhanced text mode,
there are times when the enhanced text processing is not wanted.
=46or instance, it is almost always a bad idea to treat underscores in
file names as indicating a subscript.  For this reason there is a=20
core routine ignore_enhanced(TRUE) that temporarily turns off
enhanced text processing.  ignore_enhanced(FALSE) turns is back
on again.  The routine is implemented by providing a flag variable
available to the terminal drivers:
    TBOOLEAN ignore_enhanced_text;

As best as I can make out, the wxWidgets terminal is not checking
this flag.  Therefore if the terminal is in enhanced text mode, some
strings are treated this way when they should not be.

Example:
	set termoption enhanced
	load 'histograms.dem'

In the key there are entries for "Soviet_Union" and "United_Kingdom".
Note the underscores.  It is not intended that these be typeset as
subscripts.  The x11, post, and other terminals correctly render these
text strings to contain the underscore.  The wx terminal shows instead
a subscripted next character.=20

Thanks for your detailed explanations ! I don't know why, but I must
have forgotten ignore_enhanced_text somewhen after pasting the code from
another terminal... It is working now, and my next patch will include
the fix.

Best regards,
