• you need to use two backslashes for it to be accepted as a backslash: developer.mozilla/en-US/docs/Web/JavaScript/Reference/… – Arathi Sreekumar Commented Aug 2, 2016 at 13:50

Since backslash is an escape character your string should be modified to:

"C:\\projects\\cisco\\iwan_staging_enc\\enterprise-network-controller\\ui-plugins\\iwan"

Please see: https://developer.mozilla/en-US/docs/Web/JavaScript/Reference/Global_Objects/String#Escape_notation

The \u is the start of a unicode escape sequence, in your string you have a \u not followed by four hex numbers which is the format of unicode escape sequence \uxxxx. See

"C:\projects\cisco\iwan_staging_enc\enterprise-network-controller\u0050i-plugins\iwan"

\u0050 id P

Also there there are other types of escapes, so for instance if you had a \n somewhere in there you would get a newline

"C:\new projects\cisco\iwan_staging_enc\enterprise-network-controller\u0050i-plugins\iwan"

So if you do not want avoid these escape sequences escape the \s in the string with a slash before it.

"C:\\projects\\cisco\\iwan_staging_enc\\enterprise-network-controller\\ui-plugins\\iwan"
