Conversions between UTF32, UTF-16, and UTF-8. Source code file.
|
||||||
|
Author: Mark E. Davis, 1994.
|
||||||
|
Rev History: Rick McGowan, fixes & updates May 2001.
|
||||||
|
Sept 2001: fixed const & error conditions per
|
||||||
|
mods suggested by S. Parent & A. Lillich.
|
||||||
|
June 2002: Tim Dodd added detection and handling of incomplete
|
||||||
|
source sequences, enhanced error detection, added casts
|
||||||
|
to eliminate compiler warnings.
|
||||||
|
July 2003: slight mods to back out aggressive FFFE detection.
|
||||||
|
Jan 2004: updated switches in from-UTF8 conversions.
|
||||||
|
Oct 2004: updated to use UNI_MAX_LEGAL_UTF32 in UTF-32 conversions.
|
||||||
|
|
||||||
|
See the header file "ConvertUTF.h" for complete documentation.

Note A.

The fall-through switches in UTF-8 reading code save a

|
temp variable, some decrements & conditionals. The switches
|
||||||

are equivalent to the following loop:

|

|

In UTF-8 writing code, the switches on "bytesToWrite" are
|
||||||
|
similarly unrolled loops.

Conversions between UTF32, UTF-16, and UTF-8. Header file.
|
||||||
|
|
||||||
|
Several funtions are included here, forming a complete set of
|
||||||
|
conversions between the three formats. UTF-7 is not included
|
||||||
|
here, but is handled in a separate source file.
|
||||||
|
|
||||||
|
Each of these routines takes pointers to input buffers and output
|
||||||
|
buffers. The input buffers are const.
|
||||||
|
|
||||||
|
Each routine converts the text between *sourceStart and sourceEnd,
|
||||||
|
putting the result into the buffer between *targetStart and
|
||||||
|
targetEnd. Note: the end pointers are *after* the last item: e.g.
|
||||||
|
*(sourceEnd - 1) is the last item.
|
||||||
|
|
||||||
|
The return result indicates whether the conversion was successful,
|
||||||
|
and if not, whether the problem was in the source or target buffers.
|
||||||
|
(Only the first encountered problem is indicated.)
|
||||||
|
|
||||||
|
After the conversion, *sourceStart and *targetStart are both
|
||||||
|
updated to point to the end of last text successfully converted in
|
||||||
|
the respective buffers.
|
||||||
|
|
||||||
|
Input parameters:
|
||||||
|
sourceStart - pointer to a pointer to the source buffer.
|
||||||
|
The contents of this are modified on return so that
|
||||||
|
it points at the next thing to be converted.
|
||||||
|
targetStart - similarly, pointer to pointer to the target buffer.
|
||||||
|
sourceEnd, targetEnd - respectively pointers to the ends of the
|
||||||
|
two buffers, for overflow checking only.
|
||||||
|
|
||||||
|
These conversion functions take a ConversionFlags argument. When this
|
||||||
|
flag is set to strict, both irregular sequences and isolated surrogates
|
||||||
|
will cause an error. When the flag is set to lenient, both irregular
|
||||||
|
sequences and isolated surrogates are converted.
|
||||||
|
|
||||||
|
Whether the flag is strict or lenient, all illegal sequences will cause
|
||||||
|
an error return. This includes sequences such as: <F4 90 80 80>, <C0 80>,
|
||||||
|
or <A0> in UTF-8, and values above 0x10FFFF in UTF-32. Conformant code
|
||||||
|
must check for illegal sequences.
|
||||||
|
|
||||||
|
When the flag is set to lenient, characters over 0x10FFFF are converted
|
||||||
|
to the replacement character; otherwise (when the flag is set to strict)
|
||||||
|
they constitute an error.
|
||||||
|
|
||||||
|
Output parameters:
|
||||||
|
The value "sourceIllegal" is returned from some routines if the input
|
||||||
|
sequence is malformed. When "sourceIllegal" is returned, the source
|
||||||
|
value will point to the illegal value that caused the problem. E.g.,
|
||||||
|
in UTF-8 when a sequence is malformed, it points to the start of the
|
||||||
|
malformed sequence.

/*
|
||||||
|
* This is an implementation of wcwidth() and wcswidth() (defined in
|
||||||
|
* IEEE Std 1002.1-2001) for Unicode.
|
||||||
|
*
|
||||||
|
* http://www.opengroup.org/onlinepubs/007904975/functions/wcwidth.html
|
||||||
|
* http://www.opengroup.org/onlinepubs/007904975/functions/wcswidth.html
|
||||||
|
*
|
||||||
|
* In fixed-width output devices, Latin characters all occupy a single
|
||||||
|
* "cell" position of equal width, whereas ideographic CJK characters
|
||||||
|
* occupy two such cells. Interoperability between terminal-line
|
||||||
|
* applications and (teletype-style) character terminals using the
|
||||||
|
* UTF-8 encoding requires agreement on which character should advance
|
||||||
|
* the cursor by how many cell positions. No established formal
|
||||||
|
* standards exist at present on which Unicode character shall occupy
|
||||||
|
* how many cell positions on character terminals. These routines are
|
||||||
|
* a first attempt of defining such behavior based on simple rules
|
||||||
|
* applied to data provided by the Unicode Consortium.
|
||||||
|
*
|
||||||
|
* For some graphical characters, the Unicode standard explicitly
|
||||||
|
* defines a character-cell width via the definition of the East Asian
|
||||||
|
* FullWidth (F), Wide (W), Half-width (H), and Narrow (Na) classes.
|
||||||
|
* In all these cases, there is no ambiguity about which width a
|
||||||
|
* terminal shall use. For characters in the East Asian Ambiguous (A)
|
||||||
|
* class, the width choice depends purely on a preference of backward
|
||||||
|
* compatibility with either historic CJK or Western practice.
|
||||||
|
* Choosing single-width for these characters is easy to justify as
|
||||||
|
* the appropriate long-term solution, as the CJK practice of
|
||||||
|
* displaying these characters as double-width comes from historic
|
||||||
|
* implementation simplicity (8-bit encoded characters were displayed
|
||||||
|
* single-width and 16-bit ones double-width, even for Greek,
|
||||||
|
* Cyrillic, etc.) and not any typographic considerations.
|
||||||
|
*
|
||||||
|
* Much less clear is the choice of width for the Not East Asian
|
||||||
|
* (Neutral) class. Existing practice does not dictate a width for any
|
||||||
|
* of these characters. It would nevertheless make sense
|
||||||
|
* typographically to allocate two character cells to characters such
|
||||||
|
* as for instance EM SPACE or VOLUME INTEGRAL, which cannot be
|
||||||
|
* represented adequately with a single-width glyph. The following
|
||||||
|
* routines at present merely assign a single-cell width to all
|
||||||
|
* neutral characters, in the interest of simplicity. This is not
|
||||||
|
* entirely satisfactory and should be reconsidered before
|
||||||
|
* establishing a formal standard in this area. At the moment, the
|
||||||
|
* decision which Not East Asian (Neutral) characters should be
|
||||||
|
* represented by double-width glyphs cannot yet be answered by
|
||||||
|
* applying a simple rule from the Unicode database content. Setting
|
||||||
|
* up a proper standard for the behavior of UTF-8 character terminals
|
||||||
|
* will require a careful analysis not only of each Unicode character,
|
||||||
|
* but also of each presentation form, something the author of these
|
||||||
|
* routines has avoided to do so far.
