|
|
|
11 * mbyte.c: Code specifically for handling multi-byte characters.
|
|
|
12 *
|
|
|
13 * The encoding used in the core is set with 'encoding'. When 'encoding' is
|
|
|
14 * changed, the following four variables are set (for speed).
|
|
|
15 * Currently these types of character encodings are supported:
|
|
|
16 *
|
|
|
17 * "enc_dbcs" When non-zero it tells the type of double byte character
|
|
|
18 * encoding (Chinese, Korean, Japanese, etc.).
|
|
|
19 * The cell width on the display is equal to the number of
|
|
|
20 * bytes. (exception: DBCS_JPNU with first byte 0x8e)
|
|
|
21 * Recognizing the first or second byte is difficult, it
|
|
|
22 * requires checking a byte sequence from the start.
|
|
|
23 * "enc_utf8" When TRUE use Unicode characters in UTF-8 encoding.
|
|
|
24 * The cell width on the display needs to be determined from
|
|
|
25 * the character value.
|
|
|
26 * Recognizing bytes is easy: 0xxx.xxxx is a single-byte
|
|
|
27 * char, 10xx.xxxx is a trailing byte, 11xx.xxxx is a leading
|
|
|
28 * byte of a multi-byte character.
|
|
|
29 * To make things complicated, up to two composing characters
|
|
|
30 * are allowed. These are drawn on top of the first char.
|
|
|
31 * For most editing the sequence of bytes with composing
|
|
|
32 * characters included is considered to be one character.
|
|
|
33 * "enc_unicode" When 2 use 16-bit Unicode characters (or UTF-16).
|
|
|
34 * When 4 use 32-but Unicode characters.
|
|
|
35 * Internally characters are stored in UTF-8 encoding to
|
|
|
36 * avoid NUL bytes. Conversion happens when doing I/O.
|
|
|
37 * "enc_utf8" will also be TRUE.
|
|
|
38 *
|
|
|
39 * "has_mbyte" is set when "enc_dbcs" or "enc_utf8" is non-zero.
|
|
|
40 *
|
|
|
41 * If none of these is TRUE, 8-bit bytes are used for a character. The
|
|
|
42 * encoding isn't currently specified (TODO).
|
|
|
43 *
|
|
|
44 * 'encoding' specifies the encoding used in the core. This is in registers,
|
|
|
45 * text manipulation, buffers, etc. Conversion has to be done when characters
|
|
|
46 * in another encoding are received or send:
|
|
|
47 *
|
|
|
48 * clipboard
|
|
|
49 * ^
|
|
|
50 * | (2)
|
|
|
51 * V
|
|
|
52 * +---------------+
|
|
|
53 * (1) | | (3)
|
|
|
54 * keyboard ----->| core |-----> display
|
|
|
55 * | |
|
|
|
56 * +---------------+
|
|
|
57 * ^
|
|
|
58 * | (4)
|
|
|
59 * V
|
|
|
60 * file
|
|
|
61 *
|
|
|
62 * (1) Typed characters arrive in the current locale. Conversion is to be
|
|
|
63 * done when 'encoding' is different from 'termencoding'.
|
|
|
64 * (2) Text will be made available with the encoding specified with
|
|
|
65 * 'encoding'. If this is not sufficient, system-specific conversion
|
|
|
66 * might be required.
|
|
|
67 * (3) For the GUI the correct font must be selected, no conversion done.
|
|
|
68 * Otherwise, conversion is to be done when 'encoding' differs from
|
|
|
69 * 'termencoding'. (Different in the GTK+ 2 port -- 'termencoding'
|
|
|
70 * is always used for both input and output and must always be set to
|
|
|
71 * "utf-8". gui_mch_init() does this automatically.)
|
|
|
72 * (4) The encoding of the file is specified with 'fileencoding'. Conversion
|
|
|
73 * is to be done when it's different from 'encoding'.
|
|
|
74 *
|
|
|
75 * The viminfo file is a special case: Only text is converted, not file names.
|
|
|
76 * Vim scripts may contain an ":encoding" command. This has an effect for
|
|
|
77 * some commands, like ":menutrans"

3688 * TODO: The pragmatic "put into input buffer" approach used here has

3689 * several fundamental problems:
|

3690 *
|
|
|
3691 * - The characters in the preedit string are subject to remapping.
|
|
|
3692 * That's broken, only the finally committed string should be remapped.
|
|
|
3693 *
|
|
|
3694 * - There is a race condition involved: The retrieved value for the
|
|
|
3695 * current cursor position will be wrong if any unprocessed characters
|
|
|
3696 * are still queued in the input buffer.
|
|
|
3697 *
|
|
|
3698 * - Due to the lack of synchronization between the file buffer in memory
|
|
|
3699 * and any typed characters, it's practically impossible to implement the
|
|
|
3700 * "retrieve_surrounding" and "delete_surrounding" signals reliably. IM
|
|
|
3701 * modules for languages such as Thai are likely to rely on this feature
|
|
|
3702 * for proper operation.
|
|
|
3703 *
|
|
|
3704 * Conclusions: I think support for preediting needs to be moved to the
|
|
|
3705 * core parts of Vim. Ideally, until it has been committed, the preediting
|
|
|
3706 * string should only be displayed and not affect the buffer content at all.
|
|
|
3707 * The question how to deal with the synchronization issue still remains.
|
|
|
3708 * Circumventing the input buffer is probably not desirable. Anyway, I think
|
|
|
3709 * implementing "retrieve_surrounding" is the only hard problem.
|
|
|
3710 *
|
|
|
3711 * One way to solve all of this in a clean manner would be to queue all key
|
|
|
3712 * press/release events "as is" in the input buffer, and apply the IM filtering
|
|
|
3713 * at the receiving end of the queue. This, however, would have a rather large
|
|
|
3714 * impact on the code base. If there is an easy way to force processing of all
|
|
|
3715 * remaining input from within the "retrieve_surrounding" signal handler, this
|
|
|
3716 * might not be necessary. Gotta ask on vim-dev for opinions.
