UTF-8: print from a file of codes
From JmPm
binmode(STDOUT, ":utf8"); # to silence: "Wide character in print " $in = <DATA>; $chr1=chr(hex ($in)); $string = "Hello $chr1 !\n"; print $string; __DATA__ 263a
This program brings hexadecimal data from a file and prints it as a utf8 character (if it is one). The main problem here was to change a string such as '236a' which perl cannot know is a number, into a number,because of the lack of types in perl.
