340 \class QTextCodec-
341 \inmodule QtCore-
342 \brief The QTextCodec class provides conversions between text encodings.-
343 \reentrant-
344 \ingroup i18n-
345-
346 Qt uses Unicode to store, draw and manipulate strings. In many-
347 situations you may wish to deal with data that uses a different-
348 encoding. For example, most Japanese documents are still stored-
349 in Shift-JIS or ISO 2022-JP, while Russian users often have their-
350 documents in KOI8-R or Windows-1251.-
351-
352 Qt provides a set of QTextCodec classes to help with converting-
353 non-Unicode formats to and from Unicode. You can also create your-
354 own codec classes.-
355-
356 The supported encodings are:-
357-
358 \list-
359 \li \l{Big5 Text Codec}{Big5}-
360 \li \l{Big5-HKSCS Text Codec}{Big5-HKSCS}-
361 \li CP949-
362 \li \l{EUC-JP Text Codec}{EUC-JP}-
363 \li \l{EUC-KR Text Codec}{EUC-KR}-
364 \li \l{GBK Text Codec}{GB18030}-
365 \li HP-ROMAN8-
366 \li IBM 850-
367 \li IBM 866-
368 \li IBM 874-
369 \li \l{ISO 2022-JP (JIS) Text Codec}{ISO 2022-JP}-
370 \li ISO 8859-1 to 10-
371 \li ISO 8859-13 to 16-
372 \li Iscii-Bng, Dev, Gjr, Knd, Mlm, Ori, Pnj, Tlg, and Tml-
373 \li KOI8-R-
374 \li KOI8-U-
375 \li Macintosh-
376 \li \l{Shift-JIS Text Codec}{Shift-JIS}-
377 \li TIS-620-
378 \li \l{TSCII Text Codec}{TSCII}-
379 \li UTF-8-
380 \li UTF-16-
381 \li UTF-16BE-
382 \li UTF-16LE-
383 \li UTF-32-
384 \li UTF-32BE-
385 \li UTF-32LE-
386 \li Windows-1250 to 1258-
387 \endlist-
388-
389 If Qt is compiled with ICU support enabled, most codecs supported by-
390 ICU will also be available to the application.-
391-
392 \l {QTextCodec}s can be used as follows to convert some locally encoded-
393 string to Unicode. Suppose you have some string encoded in Russian-
394 KOI8-R encoding, and want to convert it to Unicode. The simple way-
395 to do it is like this:-
396-
397 \snippet code/src_corelib_codecs_qtextcodec.cpp 0-
398-
399 After this, \c string holds the text converted to Unicode.-
400 Converting a string from Unicode to the local encoding is just as-
401 easy:-
402-
403 \snippet code/src_corelib_codecs_qtextcodec.cpp 1-
404-
405 To read or write files in various encodings, use QTextStream and-
406 its \l{QTextStream::setCodec()}{setCodec()} function. See the-
407 \l{tools/codecs}{Codecs} example for an application of QTextCodec-
408 to file I/O.-
409-
410 Some care must be taken when trying to convert the data in chunks,-
411 for example, when receiving it over a network. In such cases it is-
412 possible that a multi-byte character will be split over two-
413 chunks. At best this might result in the loss of a character and-
414 at worst cause the entire conversion to fail.-
415-
416 The approach to use in these situations is to create a QTextDecoder-
417 object for the codec and use this QTextDecoder for the whole-
418 decoding process, as shown below:-
419-
420 \snippet code/src_corelib_codecs_qtextcodec.cpp 2-
421-
422 The QTextDecoder object maintains state between chunks and therefore-
423 works correctly even if a multi-byte character is split between-
424 chunks.-
425-
426 \section1 Creating Your Own Codec Class-
427-
428 Support for new text encodings can be added to Qt by creating-
429 QTextCodec subclasses.-
430-
431 The pure virtual functions describe the encoder to the system and-
432 the coder is used as required in the different text file formats-
433 supported by QTextStream, and under X11, for the locale-specific-
434 character input and output.-
435-
436 To add support for another encoding to Qt, make a subclass of-
437 QTextCodec and implement the functions listed in the table below.-
438-
439 \table-
440 \header \li Function \li Description-
441-
442 \row \li name()-
443 \li Returns the official name for the encoding. If the-
444 encoding is listed in the-
445 \l{IANA character-sets encoding file}, the name-
446 should be the preferred MIME name for the encoding.-
447-
448 \row \li aliases()-
449 \li Returns a list of alternative names for the encoding.-
450 QTextCodec provides a default implementation that returns-
451 an empty list. For example, "ISO-8859-1" has "latin1",-
452 "CP819", "IBM819", and "iso-ir-100" as aliases.-
453-
454 \row \li \l{QTextCodec::mibEnum()}{mibEnum()}-
455 \li Return the MIB enum for the encoding if it is listed in-
456 the \l{IANA character-sets encoding file}.-
457-
458 \row \li convertToUnicode()-
459 \li Converts an 8-bit character string to Unicode.-
460-
461 \row \li convertFromUnicode()-
462 \li Converts a Unicode string to an 8-bit character string.-
463 \endtable-
