Symbols by font position

You can access any character of the current font using its number with the \symbol command. For example, the visible space character used in the \verb* command has the code decimal 32 in the standard Computer Modern typewriter font, so it can be typed as \symbol{32}.

You can also specify numbers in octal (base 8) by using a ' prefix, or hexadecimal (base 16) with a " prefix, so the visible space at 32 decimal could also be written as \symbol{'40} or \symbol{"20}.
