Will Glass-Husain commented on VELOCITY-519:
--------------------------------------------
Stepan makes good points (I believe) about the utility of including escaped
unicode characters. Actually, I face similar issues from time to time. My
main text editor doesn't do a good job with UTF-8.
I advocate \n, \r, and more importantly, \t for comprehensiveness. If we allow
unicode escaping then users will expect the other items. Are there more that
need to be included?
I can imagine cases where inserting a tab character might be useful. For
example, you might want to compare a string to \t in an #if statement. The
following
#if($samplestring.contains("\t"))
is more readable than
#if($samplestring.contains("\t"))
You could do this with a tool, but this is simpler syntax.
