If you don't want to bother with the EscapeTool, you can do this:

#set( $H = '#' )

The set technique is a good way to get around any characters you need escaping, like if you want to have $name followed by "_lastname" then you can do:

set ($n = '_lastname)

and have this in your template:

$name$n

and it's all good.
