Q:

How do I use an authenticated proxy with special char in password with JMeter

My Environment is Windows 7 (Try not to laugh) and I am using the binary download of JMeter 4.
I am trying the following command to start it...
 jmeter -H my.proxy -P 1234 -u myName -a myPassword 

My password has the # character in it. 
When I try to run my Test I get...

Response message: Proxy Authentication Required

I think it might be related to my special char given a couple other SOs. 
So how would I change this command so I can send valid requests?

A:

My password had "&" character in it. For me also, i tried url encoding i.e. %26 and it did not work. But, it worked when i tried html encoding i.e. replaced & with &amp; or &#0026;. 
For all html encoded characters, refer this wiki page. For # symbol, you can use &#0023;
