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