[jira] Commented: (PIG-838) Parser does not handle ctrl-m
('\u000d') as argument to PigStorage

Pradeep Kamath commented on PIG-838:
------------------------------------
THe issue might be because we have in QueryParser.jjt:
JAVA_UNICODE_ESCAPE = true;
which causes the parser to interpret '\u000d' as carriage return - we need for the person to not interpret these unicode escape sequences - however the above option was added to QueryParser.jjt to support unicode constants and such. So we need to find a way to support unicode characters but at the same time be able to handle '\u000d' during parsing.
