     In code, all that needs to be escaped is percent, backslash and
     unpaired braces: '% \ {'. Unescaped: '$ # _ ^ ~ < > |', and as a
     pair, '{...}'.  If we escape: ' \_ \# \$ \& { } \ ' And some
     backslashes: '\ \ \\ \\' should give one, one, two, two
     backslashes.

     How about \ (that is backslash space) in text?

     Elsewhere, { } % \ need to be escaped, but not $ # _ ^ ~ < > | .
     Let's try that again in '\samp': ' { } % \ $ # _ ^ ~ < > |'.  And
     if we do escape: \$ \# \_ , and with three backslashes, \\#.
