When printer escaping is disabled,
a character prints as itself; it is sent directly to the output stream.
When printer escaping is enabled,
then #\ syntax is used.
When the printer types out the name of a character,
it uses the same table as the #\ reader macro would use;
therefore any character name that is typed out
is acceptable as input (in that implementation).
If a non-graphic character has a standardized name_5,
that name is preferred over non-standard names
for printing in #\ notation.
For the graphic standard characters,
the character itself is always used
for printing in #\ notation—even if
the character also has a name_5.
For details about the #\ reader macro, see Sharpsign Backslash.
