read() in Spidermonkey with unicode

In the Spidermonke开发者_JS百科y shell, reading in a file with the read() function ignores the encoding of the file. Is there any way to read in a UTF-8 or other multi-byte encoded file and preserve the multi-byte characters? Spidermonkey is such a little devil.

So I talked to the JS guys at Mozilla. Turns out this wasn't entirely possible, so they added a command line flag to enable UTF-8 support for read() and snarf().

/usr/bin/js -e "print(read('filexyz.txt'))" -U

In order to get a copy of Spidermonkey with this addition, you'll have to use the Tracemonkey repository. You can get that with Mercurial:

hg clone http://hg.mozilla.org/tracemonkey/
