IE8 + utf-8 problem, part 2

[plentz]

I've found another situation where quoting is needed. if you have a key, like this

{ÿ:"3"}

IE8+(9, 10 and 11, also) will fail, so I think that the right behavior is to make :quote_keys => true the default.

I'm not able to replicate this with the example input. What JS runtime are you using?

this is the file generated by uglifier: https://gist.github.com/plentz/5d07c59019678ef663c7

and this is the message showed in IE8

I think it can be related to this piece

...ò:{d:"83,-199v56...

This seems to be caused by serving the file without charset header, in which case IE assumes that the file is encoded in Latin-1. In addition to using ascii_only: true, the issue can be fixed by using Content-Type: application/javascript; charset=UTF-8 or with `charset="UTF-8" attribute in the script tag.
