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.

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.
