#10288 closed bug (invalid)
1.6.4 minified has high order bytes causing IE 8 crash when not sent UTF-8

Description
If you serve 1.6.4 under lighttpd for instance, which does not set a charset (default will be ISO-8859-1), it will crash IE8.
Pulling same library from google, which sets UTF-8, it does not crash
There is a space character that is not 7 bit ascii starting at character # 15119
(I know there is a better way to do this, but it works) hexdump -v -e '1/1 "%02X" "\n"' jquery-1.6.4.min.js | awk '/[8-9A-F]/ {print NR " " $0} /[0-7]?/ {}'
search for j.test("
Fix: Use the non-minified version, or you can yui minify the unminified version and it will not have the 8 bit characters

It's commented out:
# "mod_compress",
I'm curious from the response if you disagree about the existence of the 2 8-bit bytes, or if the high bytes are intended, or if you are asserting that it shouldn't matter?
To be a little more explicit, Here are two versions of jquery and the test I ran (Mac OSX):
curl -o jquery-1.6.4.min.js http://code.jquery.com/jquery-1.6.4.min.js hexdump -v -e '1/1 "%02X" "\n"' jquery-1.6.4.min.js | awk '/[8-9A-F]/ {print NR " " $0} /[0-7]?/ {}'
The output shows any bytes in the range 80-FF (hex): 15119 C2 15120 A0
curl -o jquery-1.6.4.js http://code.jquery.com/jquery-1.6.4.js hexdump -v -e '1/1 "%02X" "\n"' jquery-1.6.4.js | awk '/[8-9A-F]/ {print NR " " $0} /[0-7]?/ {}' (no output, it's clean)
I also checked http://code.jquery.com/jquery.min.js and it has 8 bit bytes
For more detail on the lighttpd, environment has already been modified (outside my control), so I can't show the crash state anymore, but this should be the matching set of response headers I just pulled from a different environment for jquery-1.6.4.min.js:
Accept-Ranges:bytes Content-Length:72174 Content-Type:text/javascript Date:Fri, 16 Sep 2011 15:55:39 GMT ETag:"-1556017200" Last-Modified:Mon, 07 Jun 2010 22:52:02 GMT Server:NENlighttpd
thanks -c

oops, I didn't use wiki formatting and posted anonymously instead of with my addy, the code should instead be:
hexdump -v -e '1/1 "%02X" "\n"' jquery-1.6.4.min.js \ | awk '/^[8-9A-F]/ {print NR " " $0} /[0-7]?/ {}'
I don't think I can edit my earlier comment to fix

This problem could not be confirmed and has not been reported in recent versions.
Are you using lighty's ModCompress? If so disable it and see if the problem is still there.
