Bug 180105 – jsc binary operates on UTF-8-encoded bytes rather than actual source text

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: JavaScriptCore

[Mathias Bynens]

There is a difference between input entered directly into the jsc REPL (through a terminal set to UTF-8) vs. passed as a file (saved with UTF-8 encoding).

    $ jsc -e 'print("\xCF\x80" === "π")'
    false

    $ jsc
    >>> print("\xCF\x80" === "π")
    true

This might lead people to (incorrectly!) believe that e.g. jsc’s implementation of Unicode property escapes is broken:

    $ jsc
    >>> /\p{Script=Greek}/u.test("π")
    false

    $ jsc -e 'print(/\p{Script=Greek}/u.test("π"))'
    true
