> Some investigation has revealed the following:
>
> 1. When you use a string literal the template actually contains a  
> carriage
> return and a new line
> 2. When you read the template from an embedded resource the template
> contains "\r\n" instead of a carriage return and a new line
>
> The second case sends the lexer down a path where \r is not defined  
> as a
> valid escape character. I've just uploaded a new C# version to
> www.stringtemplate.org which fixes this problem.
