converting hex or numerics to characters?

[d_eberhard]

Which editor can take hex numbers (i.e. %3C ) or numeric representations (i.e. h) and convert them to their matching characters and vice versa?

note: using javascript to write these results to psuedu-encrypt web page content, etc.

examples:

%3C = "<" (the less-than sign)

&#104; = "h" (small letter h)

I'd like to be able to use such encrypting to hide e-mail links and other page elements from robots, etc.

Appreciate your help.

Almost all the good text editors can do the hex conversion one by one. Nothing that has a macro that I know of.
