[dokuwiki] Re: Abbreviations or Explain plug-in?

Andi,
        Thanks for your quick reply.  Sorry for my late reply...this "best 
effort" project was delayed by the boss.

        I did and it didn't work for me, thus my posted questions.  I just 
assumed I was running into a syntax limitation.  Based on your input, I've done 
some more tests since.  I didn't test without $ before since all of my user's 
pages are configuration templates which use a $value1_value2$ placeholder 
syntax.  I tested today using {value1_value2} instead and it worked, so it does 
appear that $ is not an allowed character in abbreviations and what was causing 
my earlier test failures.

        Due to { test success, I tested an additional subset of UTF-8 
characters from x21-x2f.  All of them work in abbreviations except for #, $, ( 
& ).


        I thought at first that $ might not work because the abbreviations are 
passed through the Doku_Lexer_Escape function so the $ characters would be 
escaped.  But many of the working characters in my test range are escaped as 
well and the three other non-working characters are not, yet they don't work.  
That said, I find that if I alter the $escaped array in Doku_Lexer_Escape from 
'\$' to '\\\$' then my $value$ acronyms will work.

        I'd really appreciate any further thoughts you have on this, especially 
on whether my change could potentially have nasty impacts to other parts of my 
install, should I apply it permanently.

Thanks,

Bobby
