Escape chars in user language (patch included

[Ignazio Di Napoli]

Hi everyone.
I've just started using Notepad++ and find it wonderful. I found a problem in user language syntax hilighting because it does not allow escape characters in strings (as in " \" "). I modified the lexer to allow them (patch attached), but I did not provide a patch for the user interface. You have to modify userDefineLang.xml to include the escape chars at the end of the delimiters (so that, for example, you have the value <"00"00\00>). I hope the setting is not lost when modifying the definition using the GUI.
I hope I have been useful.

Thank you,
Ignazio

Good to know this is a request that many more users have. Now you have created an solution, it would be great if it the feature would be implemented.
We have a workbench to create DSL's and we generate userDefineLang.xml files to support Notepad++ users, but are limited in supporting Strings now.
