# These mapping tables and character lists are subject to change.

#
# For general information about Mac OS encodings and these mapping
# tables, see the file "README.TXT".
#
# Format:
# -------
#
# Three tab-separated columns;
# '#' begins a comment which continues to the end of the line.
# Column #1 is the Mac OS Gujarati code or code sequence
# (in hex as 0xNN or 0xNN+0xNN)
# Column #2 is the corresponding Unicode or Unicode sequence
# (in hex as 0xNNNN or 0xNNNN+0xNNNN).
# Column #3 is a comment containing the Unicode name or sequence
# of names. In some cases an additional comment follows the
# Unicode name(s).
#
# The entries are in two sections. The first section is for pairs of
# Mac OS Gujarati code points that must be mapped in a special way.
# The second section maps individual code points.
#
# Within each section, the entries are in Mac OS Gujarati code order.
#
# Control character mappings are not shown in this table, following
# the conventions of the standard UTC mapping tables. However, the
# Mac OS Gujarati character set uses the standard control characters
# at 0x00-0x1F and 0x7F.
#
# 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:
