Returns the result of decoding the provided text from UTF-8.
$utfdecode(text, C)

The parameter C is an 8-bit (0-255) number referencing a GDI charset number for specific code page to unicode resolution.

== Available charset numbers ==

for a list of available charset numbers, see [[$utfencode#Available charset numbers|$utfencode]].

== Actual transition ==

Behind the scene, $utfdecode does the inverted operation of $utfencode, which is the following:
# Unicode char code is encoded using [[$utfencode]] to form its UTF-8 analogue.
# Looks up the char code in unicode's charset map to be of what abstract character, e.g. for C the abstract character is LATIN CAPITAL LETTER C.
# The abstract character is located in the given charset map.
# The located char code is used to encode the char in the given charset map encoding.

Decoding UTF-8 with code page references is more intricate and, at present, slightly flawed insofar as mIRC will attempt to decode invalid UTF-8.

== Examples ==
[[$asc]]($utfdecode([[$utfencode]]([[$chr]](915)), 161))
This example will return 195, which is the ANSI char code of the greek capital letter Gamma.
