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, \\#.

a < b > c | d, x^y

\$k > \#k, x_y, x\_y

group-weighting from $[N_iP_i(1-P_i)]$

        % a
        \
        \% c
        {
        \{

### URLs and emails

URLs need to be verbatim: testit ~^_$#<>|.
