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