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 six composing characters |
7 | 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" | |

4498 * | |
4499 * TODO: The pragmatic "put into input buffer" approach used here has | |
4500 * several fundamental problems: | |
4501 * | |
4502 * - The characters in the preedit string are subject to remapping. | |
4503 * That's broken, only the finally committed string should be remapped. | |
4504 * | |
4505 * - There is a race condition involved: The retrieved value for the | |
4506 * current cursor position will be wrong if any unprocessed characters | |
4507 * are still queued in the input buffer. | |
4508 * | |
4509 * - Due to the lack of synchronization between the file buffer in memory | |
4510 * and any typed characters, it's practically impossible to implement the | |
4511 * "retrieve_surrounding" and "delete_surrounding" signals reliably. IM | |
4512 * modules for languages such as Thai are likely to rely on this feature | |
4513 * for proper operation. | |
4514 * | |
4515 * Conclusions: I think support for preediting needs to be moved to the | |
4516 * core parts of Vim. Ideally, until it has been committed, the preediting | |
4517 * string should only be displayed and not affect the buffer content at all. | |
4518 * The question how to deal with the synchronization issue still remains. | |
4519 * Circumventing the input buffer is probably not desirable. Anyway, I think | |
4520 * implementing "retrieve_surrounding" is the only hard problem. | |
4521 * | |
4522 * One way to solve all of this in a clean manner would be to queue all key | |
4523 * press/release events "as is" in the input buffer, and apply the IM filtering | |
4524 * at the receiving end of the queue. This, however, would have a rather large | |
4525 * impact on the code base. If there is an easy way to force processing of all | |
4526 * remaining input from within the "retrieve_surrounding" signal handler, this | |
4527 * might not be necessary. Gotta ask on vim-dev for opinions. | |
