Nathan Bubna commented on VELOCITY-519:
---------------------------------------
The only consensus here is that we should fix the lexer error when \uXXXX
appears in a string definition. This would be Stepan's second attached patch.
And yes, this will allow you to insert tabs, carriage returns and line feeds by
typing *six* characters for each instead of just typing the one tab, CR or LF
character. why do:
#set( $tab = "\u0009" )
which doesn't even work yet, when
#set( $tab = " " )
already works?
> Java escape sequences should work in Velocity macros
