javascript - ToLocaleDateString() changes in IE11

Question

In IE 11, I'm getting funny results with ToLocaleDateString(). The string returned looks fine in the browser, e.g. "1/28/2014 11:00:46 AM", but then if I copy and paste that value into a plain text editor, it looks like this: "?1?/?28?/?2014 ?11?:?00?:?46? ?AM".

Interestingly, if I paste the text into a Microsoft product, it looks fine... The issue is that if you try to use the value programmatically to create a date, it's invalid. You can test this by just opening up a console in IE11 and creating a new date, using ToLocaleDateString() on it, and then trying to use the resulting string to create a new date in javascript or in the language of your choice (I'm using ASP.NET here...).

Am I doing something wrong, or is there some other way I'm supposed to be interacting with the javascript Date? How can I get rid of those funky symbols?

Edit: Thanks to the comment below I was able to figure out what the unshown characters are, they're Left-To-Right marks. Depending on the editor I paste the values into and the encoding that the editor is set to use, the text will show up differently: sometimes with "?", sometimes without.

I fixed that with the following replace(/[^ -~]/g,'') as in

(new Date("7/15/2014").toLocaleString().replace(/[^ -~]/g,'')
