Michael Jumper reopened GUACAMOLE-437:
--------------------------------------

Apparently a UTF-8 non-breaking space was accidentally inserted with these changes:

{code:none}
00000000: 2020 2020 7661 7220 6578 7472 6148 6561      var extraHea
00000010: 6465 7273 203d 2065 7874 7261 5475 6e6e  ders = extraTunn
00000020: 656c 4865 6164 6572 7320 7c7c c2a0 7b7d  elHeaders ||..{}
00000030: 3b0a                    
{code}

The space to the left of the two pipe symbols is a normal U+0020 space, however the space to the right is actually U+00A0. This has the side effect of being misinterpreted as "Â" if the JavaScript is read as ISO 8859-1 / CP-1252.

> When establishing a Guacamole tunnel to an endpoint that requires (for example) authentication, it is often needed to send custom headers. The existing withCredentials option works well for session cookies in cross-domain environments, but when there are no sessions or authentication relies on headers, there is no way to have an authenticated tunnel request.
> A mechanism to configure custom headers for Guacamole tunnels would allow users to configure custom headers that might be needed for their systems, such as authentication headers, distributed tracing correlation headers, request signatures, etc.
