setting. It can be built by setting the WITH_ICONV knob. While this knob is unset, the library part, the binaries, the header file and the metadata files will not be built or installed so it makes no impact on the system if left turned off. This work is based on the iconv implementation in NetBSD but a great number of improvements and feature additions have been included: - Some utilities have been added. There is a conversion table generator, which can compare conversion tables to reference data generated by GNU libiconv. This helps ensuring conversion compatibility. - UTF-16 surrogate support and some endianness issues have been fixed. - The rather chaotic Makefiles to build metadata have been refactored and cleaned up, now it is easy to read and it is also easier to add support for new encodings. - A bunch of new encodings and encoding aliases have been added. - Support for 1->2, 1->3 and 1->4 mappings, which is needed for transliterating with flying accents as GNU does, like "u. - Lots of warnings have been fixed, the major part of the code is now WARNS=6 clean. - New section 1 and section 5 manual pages have been added. - Some GNU-specific calls have been implemented: iconvlist(), iconvctl(), iconv_canonicalize(), iconv_open_into() - Support for GNU's //IGNORE suffix has been added. - The "-" argument for stdin is now recognized in iconv(1) as per POSIX. - The Big5 conversion module has been fixed. - The iconv.h header files is supposed to be compatible with the GNU version, i.e. sources should build with base iconv.h and GNU libiconv. It also includes a macro magic to deal with the char ** and const char ** incompatibility. - GNU compatibility: "" or "char" means the current local encoding in use - Various cleanups and style(9) fixes.

# '#' begins a comment which continues to the end of the line.
|
|
# Column #1 is the Mac OS Gujarati code or code sequence

|
|
# Notes on Mac OS Gujarati:
|
|
# -------------------------
|
|
#
|
|
# This is a legacy Mac OS encoding; in the Mac OS X Carbon and Cocoa
|
|
# environments, it is only supported via transcoding to and from
|
|
# Unicode.
|
|
#
|
|
# Mac OS Gujarati is based on IS 13194:1991 (ISCII-91), with the
|
|
# addition of several punctuation and symbol characters. However,
|
|
# Mac OS Gujarati does not support the ATR (attribute) mechanism of
|
|
# ISCII-91.
|
|
#
|
|
# 1. ISCII-91 features in Mac OS Gujarati include:
|
|
#
|
|
# a) Overloading of nukta
|
|
#
|
|
# In addition to using the nukta (0xE9) like a combining dot below,
|
|
# nukta is overloaded to function as a general character modifier.
|
|
# In this role, certain code points followed by 0xE9 are treated as
|
|
# a two-byte code point representing a character which may be
|
|
# rather different than the characters represented by either of
|
|
# the code points alone. For example, the character GUJARATI OM
|
|
# (U+0AD0) is represented in ISCII-91 as candrabindu + nukta.
|
|
#
|
|
# b) Explicit halant and soft halant
|
|
#
|
|
# A double halant (0xE8 + 0xE8) constitutes an "explicit halant",
|
|
# which will always appear as a halant instead of causing formation
|
|
# of a ligature or half-form consonant.
|
|
#
|
|
# Halant followed by nukta (0xE8 + 0xE9) constitutes a "soft
|
|
# halant", which prevents formation of a ligature and instead
|
|
# retains the half-form of the first consonant.
|
|
#
|
|
# c) Invisible consonant
|
|
#
|
|
# The byte 0xD9 (called INV in ISCII-91) is an invisible consonant:
|
|
# It behaves like a consonant but has no visible appearance. It is
|
|
# intended to be used (often in combination with halant) to display
|
|
# dependent forms in isolation, such as the RA forms or consonant
|
|
# half-forms.
|
|
#
|
|
# d) Extensions for Vedic, etc.
|
|
#
|
|
# The byte 0xF0 (called EXT in ISCII-91) followed by any byte in
|
|
# the range 0xA1-0xEE constitutes a two-byte code point which can
|
|
# be used to represent additional characters for Vedic (or other
|
|
# extensions); 0xF0 followed by any other byte value constitutes
|
|
# malformed text. Mac OS Gujarati supports this mechanism, but
|
|
# does not currently map any of these two-byte code points to
|
|
# anything.
|
|
#
|
|
# 2. Mac OS Gujarati additions
|
|
#
|
|
# Mac OS Gujarati adds characters using the code points
|
|
# 0x80-0x8A and 0x90.
|
|
#
|
|
# 3. Unused code points
|
|
#
|
|
# The following code points are currently unused, and are not shown
|
|
# here: 0x8B-0x8F, 0x91-0xA0, 0xAB, 0xAF, 0xC7, 0xCE, 0xD0, 0xD3,
|
|
# 0xE0, 0xE4, 0xEB-0xEF, 0xFB-0xFF. In addition, 0xF0 is not shown
|
|
# here, but it has a special function as described above.
|
|
#
|
|
# Unicode mapping issues and notes:
|
|
# ---------------------------------
|
|
#
|
|
# 1. Mapping the byte pairs
|
|
#
|
|
# If one of the following byte values is encountered when mapping
|
|
# Mac OS Gujarati text - xA1, xAA, xDF, or 0xE8 - then the next
|
|
# byte (if there is one) should be examined. If the next byte is
|
|
# 0xE9 - or also 0xE8, if the first byte was 0xE8 - then the byte
|
|
# pair should be mapped using the first section of the mapping
|
|
# table below. Otherwise, each byte should be mapped using the
|
|
# second section of the mapping table below.
|
|
#
|
|
# - The Unicode Standard, Version 2.0, specifies how explicit
|
|
# halant and soft halant should be represented in Unicode;
|
|
# these mappings are used below.
|
|
#
|
|
# If the byte value 0xF0 is encountered when mapping Mac OS
|
|
# Gujarati text, then the next byte should be examined. If there
|
|
# is no next byte (e.g. 0xF0 at end of buffer), the mapping
|
|
# process should indicate incomplete character. If there is a next
|
|
# byte but it is not in the range 0xA1-0xEE, the mapping process
|
|
# should indicate malformed text. Otherwise, the mapping process
|
|
# should treat the byte pair as a valid two-byte code point with no
|
|
# mapping (e.g. map it to QUESTION MARK, REPLACEMENT CHARACTER,
|
|
# etc.).
|
|
#
|
|
# 2. Mapping the invisible consonant
|
|
#
|
|
# It has been suggested that INV in ISCII-91 should map to ZERO
|
|
# WIDTH NON-JOINER in Unicode. However, this causes problems with
|
|
# roundtrip fidelity: The ISCII-91 sequences 0xE8+0xE8 and 0xE8+0xD9
|
|
# would map to the same sequence of Unicode characters. We have
|
|
# instead mapped INV to LEFT-TO-RIGHT MARK, which avoids these
|
|
# problems.
|
|
#
|
|
# Details of mapping changes in each version:
