[Plplot-devel] plsesc()

[<hba...@ma...>]

Hello,

I believe that it would be convenient to allow a wider range of  
escape characters in plsesc(). I would like to write a wrapper for  
some of plplot's text handling capabilities. One part of this wrapper  
involves using functions like superscript(), subscript(), etc..  
instead of #u, #d, etc.. so that the end user doesn't have to  
remember, or even be aware of, plplot's escape sequences. This is  
made challenging however by the fact that the user can easily put any  
of the currently available escape characters into their strings. For  
example, when you run onto the string "#dark" was that because the  
user entered "#dark", and now you need to change that to "##dark" so  
that it will be displayed properly, or because they entered 'subscript 
("ark")', in which case you should not do anything? Is it reasonable  
to add a non-printable esc character such as <esc> itself?

thanks,
