It is used in the mapping of some IBM encodings for Korean, such as IBM code page 933, which allows the use of the Shift Out and Shift In characters to shift to a double-byte character set. [5] Since the double-byte character set could contain compatibility jamo, halfwidth variants are needed to provide round-trip compatibility. [6] [7]
A wide character refers to the size of the datatype in memory. It does not state how each value in a character set is defined. Those values are instead defined using character sets, with UCS and Unicode simply being two common character sets that encode more characters than an 8-bit wide numeric value (255 total) would allow.
Sed regular expressions, particularly those using the "s" operator, are much similar to Perl (sed is a predecessor to Perl). The default delimiter is "/", but any delimiter can be used; the default is s / regexp / replacement / , but s : regexp : replacement : is also a valid form.
The hash mark character introduces a comment in Perl, which runs up to the end of the line of code and is ignored by the compiler (except on Windows). The comment used here is of a special kind: it’s called the shebang line.
This includes Perl itself, nearly all publicly released modules, many scripts, most design documents, many articles on Perl.com and other Perl-related web sites, and the Parrot virtual machine. Pod is rarely read in the raw, although it is designed to be readable without the assistance of a formatting tool.

A numeric value is represented as a sequence of space and tab characters that represent 0 and 1 respectively and terminated by a linefeed. The first character represents the sign of the value – space for positive and tab for negative. Subsequent characters before the terminator represent the binary digits of a value. For example:
String literals can be written using character ordinals. New syntax for subroutine attributes. (The attrs pragma is now deprecated.) Support for large files, where available. Support for binary numbers. JPL ("Java Perl Lingo") distribution comes bundled with Perl. Much new documentation in the form of tutorials and reference information has ...
