# If this converter alias table looks very confusing, a much easier to
# understand view can be found at this demo:
# http://demo.icu-project.org/icu-bin/convexp

# IMPORTANT NOTE
#
# This file is not read directly by ICU. If you change it, you need to
# run gencnval, and eventually run pkgdata to update the representation that
# ICU uses for aliases. The gencnval tool will normally compile this file into
# cnvalias.icu. The gencnval -v verbose option will help you when you edit
# this file.

# Please be friendly to the rest of us that edit this table by
# keeping this table free of tabs.

# This is an alias file used by the character set converter.
# A lot of converter information can be found in unicode/ucnv.h, but here
# is more information about this file.
# 
# If you are adding a new converter to this list and want to include it in the
# icu data library, please be sure to add an entry to the appropriate ucm*.mk file
# (see ucmfiles.mk for more information).
# 
# Here is the file format using BNF-like syntax:
#
# converterTable ::= tags { converterLine* }
# converterLine ::= converterName [ tags ] { taggedAlias* }'\n'
# taggedAlias ::= alias [ tags ]
# tags ::= '{' { tag+ } '}'
# tag ::= standard['*']
# converterName ::= [0-9a-zA-Z:_'-']+
# alias ::= converterName
#
# Except for the converter name, aliases are case insensitive.
# Names are separated by whitespace.
# Line continuation and comment sytax are similar to the GNU make syntax.
# Any lines beginning with whitespace (e.g. U+0020 SPACE or U+0009 HORIZONTAL
# TABULATION) are presumed to be a continuation of the previous line.
# The # symbol starts a comment and the comment continues till the end of
# the line.
#
# The converter
#
# All names can be tagged by including a space-separated list of tags in
# curly braces, as in ISO_8859-1:1987{IANA*} iso-8859-1 { MIME* } or
# some-charset{MIME* IANA*}. The order of tags does not matter, and
# whitespace is allowed between the tagged name and the tags list.
#
# The tags can be used to get standard names using ucnv_getStandardName().
#
# The complete list of recognized tags used in this file is defined in
# the affinity list near the beginning of the file.
#
# The * after the standard tag denotes that the previous alias is the
# preferred (default) charset name for that standard. There can only
# be one of these default charset names per converter.


# The world is getting more complicated...
# Supporting XML parsers, HTML, MIME, and similar applications
# that mark encodings with a charset name can be difficult.
# Many of these applications and operating systems will update
# their codepages over time.

# It means that a new codepage, one that differs from an
# old one by changing a code point, e.g., to the Euro sign,
# must not get an old alias, because it would mean that
# old files with this alias would be interpreted differently.

# If an codepage gets updated by assigning characters to previously
# unassigned code points, then a new name is not necessary.
# Also, some codepages map unassigned codepage byte values
# to the same numbers in Unicode for roundtripping. It may be
# industry practice to keep the encoding name in such a case, too
# (example: Windows codepages).

# The aliases listed in the list of character sets
# that is maintained by the IANA (http://www.iana.org/) must
# not be changed to mean encodings different from what this
# list shows. Currently, the IANA list is at
# http://www.iana.org/assignments/character-sets
# It should also be mentioned that the exact mapping table used for each
# IANA names usually isn't specified. This means that some other applications
# and operating systems are left to interpret the exact mappings for the
# underspecified aliases. For instance, Shift-JIS on a Solaris platform
# may be different from Shift-JIS on a Windows platform. This is why
# some of the aliases can be tagged to differentiate different mapping
# tables with the same alias. If an alias is given to more than one converter,
# it is considered to be an ambiguous alias, and the affinity list will
# choose the converter to use when a standard isn't specified with the alias.

# Name matching is case-insensitive. Also, dashes '-', underscores '_'
# and spaces ' ' are ignored in names (thus cs-iso_latin-1, csisolatin1
# and "cs iso latin 1" are the same).
# However, the names in the left column are directly file names
# or names of algorithmic converters, and their case must not
# be changed - or else code and/or file names must also be changed.
# For example, the converter ibm-921 is expected to be the file ibm-921.cnv.


# The immediately following list is the affinity list of supported standard tags.
# When multiple converters have the same alias under different standards,
# the standard nearest to the top of this list with that alias will
# be the first converter that will be opened. The ordering of the aliases
# after this affinity list does not affect the preferred alias, but it may
# affect the order of the returned list of aliases for a given converter.
#
# The general ordering is from specific and frequently used to more general
# or rarely used at the bottom.
