Benjamin Reed commented on PIG-123:
-----------------------------------
It would be nice to fix this properly and allow support for specifying unicode
characters, \uXXXX , and supporting standard escapes, \r \n \t. As you mention,
we have to introduce a semantic change, so we should do it right.
BTW, make sure to test for '\\' and '\\\''.

> Reporter: andrei badulescu

> a query like this :
> filter c by ( c.string eq 'hell\'s angels' OR c.string eq 'blue\'s clues')
> generates an error with the pig parser, because the parser does not allow
> single quotes (') within single quotes, even if they are escaped with a
> backslash.
