This is great. Thank you! So like most things in computing, the zeros are omitted, so \x{A} is actually \x{000A}.	[reply]

You're most welcome, three18ti! Perl expectedly parses both as `"\n"` (the leading zeros aren't significant): `perl -MO=Deparse,-p -e 'print "\x{A}"'` [download] Output: `print("\n"); -e syntax OK` [download] And: `use warnings; use strict; print ord "\x{A}" if "\x{000A}" eq "\n";` [download] Output: `10` [download] As you see, `\x{A}`, `\x{000A}` and `\n` all represent the same character.
