334 \class QTextCodec-
335 \inmodule QtCore-
336 \brief The QTextCodec class provides conversions between text encodings.-
337 \reentrant-
338 \ingroup i18n-
339-
340 Qt uses Unicode to store, draw and manipulate strings. In many-
341 situations you may wish to deal with data that uses a different-
342 encoding. For example, most Japanese documents are still stored-
343 in Shift-JIS or ISO 2022-JP, while Russian users often have their-
344 documents in KOI8-R or Windows-1251.-
345-
346 Qt provides a set of QTextCodec classes to help with converting-
347 non-Unicode formats to and from Unicode. You can also create your-
348 own codec classes.-
349-
350 The supported encodings are:-
351-
352 \list-
353 \li \l{Big5 Text Codec}{Big5}-
354 \li \l{Big5-HKSCS Text Codec}{Big5-HKSCS}-
355 \li CP949-
356 \li \l{EUC-JP Text Codec}{EUC-JP}-
357 \li \l{EUC-KR Text Codec}{EUC-KR}-
358 \li \l{GBK Text Codec}{GB18030}-
359 \li HP-ROMAN8-
360 \li IBM 850-
361 \li IBM 866-
362 \li IBM 874-
363 \li \l{ISO 2022-JP (JIS) Text Codec}{ISO 2022-JP}-
364 \li ISO 8859-1 to 10-
365 \li ISO 8859-13 to 16-
366 \li Iscii-Bng, Dev, Gjr, Knd, Mlm, Ori, Pnj, Tlg, and Tml-
367 \li KOI8-R-
368 \li KOI8-U-
369 \li Macintosh-
370 \li \l{Shift-JIS Text Codec}{Shift-JIS}-
371 \li TIS-620-
372 \li \l{TSCII Text Codec}{TSCII}-
373 \li UTF-8-
374 \li UTF-16-
375 \li UTF-16BE-
376 \li UTF-16LE-
377 \li UTF-32-
378 \li UTF-32BE-
379 \li UTF-32LE-
380 \li Windows-1250 to 1258-
381 \endlist-
382-
383 If Qt is compiled with ICU support enabled, most codecs supported by-
384 ICU will also be available to the application.-
385-
386 \l {QTextCodec}s can be used as follows to convert some locally encoded-
387 string to Unicode. Suppose you have some string encoded in Russian-
388 KOI8-R encoding, and want to convert it to Unicode. The simple way-
389 to do it is like this:-
390-
391 \snippet code/src_corelib_codecs_qtextcodec.cpp 0-
392-
393 After this, \c string holds the text converted to Unicode.-
394 Converting a string from Unicode to the local encoding is just as-
395 easy:-
396-
397 \snippet code/src_corelib_codecs_qtextcodec.cpp 1-
398-
399 To read or write files in various encodings, use QTextStream and-
400 its \l{QTextStream::setCodec()}{setCodec()} function. See the-
401 \l{tools/codecs}{Codecs} example for an application of QTextCodec-
402 to file I/O.-
403-
404 Some care must be taken when trying to convert the data in chunks,-
405 for example, when receiving it over a network. In such cases it is-
406 possible that a multi-byte character will be split over two-
407 chunks. At best this might result in the loss of a character and-
408 at worst cause the entire conversion to fail.-
409-
410 The approach to use in these situations is to create a QTextDecoder-
411 object for the codec and use this QTextDecoder for the whole-
412 decoding process, as shown below:-
413-
414 \snippet code/src_corelib_codecs_qtextcodec.cpp 2-
415-
416 The QTextDecoder object maintains state between chunks and therefore-
417 works correctly even if a multi-byte character is split between-
418 chunks.-
419-
420 \section1 Creating Your Own Codec Class-
421-
422 Support for new text encodings can be added to Qt by creating-
423 QTextCodec subclasses.-
424-
425 The pure virtual functions describe the encoder to the system and-
426 the coder is used as required in the different text file formats-
427 supported by QTextStream, and under X11, for the locale-specific-
428 character input and output.-
429-
430 To add support for another encoding to Qt, make a subclass of-
431 QTextCodec and implement the functions listed in the table below.-
432-
433 \table-
434 \header \li Function \li Description-
435-
436 \row \li name()-
437 \li Returns the official name for the encoding. If the-
438 encoding is listed in the-
439 \l{IANA character-sets encoding file}, the name-
440 should be the preferred MIME name for the encoding.-
441-
442 \row \li aliases()-
443 \li Returns a list of alternative names for the encoding.-
444 QTextCodec provides a default implementation that returns-
445 an empty list. For example, "ISO-8859-1" has "latin1",-
446 "CP819", "IBM819", and "iso-ir-100" as aliases.-
447-
448 \row \li \l{QTextCodec::mibEnum()}{mibEnum()}-
449 \li Return the MIB enum for the encoding if it is listed in-
450 the \l{IANA character-sets encoding file}.-
451-
452 \row \li convertToUnicode()-
453 \li Converts an 8-bit character string to Unicode.-
454-
455 \row \li convertFromUnicode()-
456 \li Converts a Unicode string to an 8-bit character string.-
457 \endtable-
