487010 - Add option to allow unicode format-control characters

Status: RESOLVED INACTIVE

(Rhino Graveyard :: Core, defect)

Section 7.1 of ECMA definition is clear concerning unicode format-control characters: 
-----------------------
"... These characters are removed from the source text before applying the lexical grammar. Since these characters are
removed before processing string and regular expression literals, one
must use a. Unicode escape sequence
(see 7.6) to include a Unicode format-control character inside a
string or regular expression literal."
-----------------------

And this is verified by standard test ecma_3/Unicode/uc-001.js which (approximatively) tests that:

  "no error" === eval('"no\u200E error"')

The problem for HtmlUnit is that none of the "normal" browsers respect that and all accept unicode format-control characters.

The consequence is that we would need a possibility to configure Rhino to consider these characters as normal characters rather than to dismiss them.

What would be the best way for that? Once this is defined, I can provide a patch.

Reproducible: Always
