DESCRIPTION
       The QHebrewCodec class provides conversion to and from visually ordered
       Hebrew.

       Hebrew as a semitic language is written from right to left. Because
       older computer systems couldn't handle reordering a string so that the
       first letter appears on the right, many older documents were encoded in
       visual order, so that the first letter of a line is the rightmost one
       in the string.

       In contrast to this, Unicode defines characters to be in logical order
       (the order you would read the string). This codec tries to convert
       visually ordered Hebrew (8859-8) to Unicode. This might not always work
       perfectly, because reversing the bidi (bi-directional) algorithm that
       transforms from logical to visual order is non-trivial.

       Transformation from Unicode to visual Hebrew (8859-8) is done using the
       bidi algorithm in Qt, and will produce correct results, so long as the
       codec is given the text a whole paragraph at a time. Places where
       newlines are supposed to go can be indicated by a newline character
       ('\n'). Note that these newline characters change the reordering
       behaviour of the algorithm, since the bidi reordering only takes place
       within one line of text, whereas line breaks are determined in visual
       order.

       Visually ordered Hebrew is still used quite often in some places,
       mainly in email communication (since most email programs still don't
       understand logically ordered Hebrew) and on web pages. The use on web
       pages is rapidly decreasing, due to the availability of browsers that
       correctly support logically ordered Hebrew.

       This codec has the name "iso8859-8". If you don't want any bidi
       reordering to happen during conversion, use the "iso8859-8-i" codec,
       which assumes logical order for the 8-bit string.

       See also Internationalization with Qt.

MEMBER FUNCTION DOCUMENTATION
QCString QHebrewCodec::fromUnicode ( const QString & uc, int & lenInOut )
       const [virtual]
       Transforms the logically ordered QString, uc, into a visually ordered
       string in the 8859-8 encoding. Qt's bidi algorithm is used to perform
       this task. Note that newline characters affect the reordering, since
       reordering is done on a line by line basis.

       The algorithm is designed to work on whole paragraphs of text, so
       processing a line at a time may produce incorrect results. This
       approach is taken because the reordering of the contents of a
       particular line in a paragraph may depend on the previous line in the
       same paragraph.

       Some encodings (for example Japanese or UTF-8) are multibyte (so one
       input character is mapped to two output characters). The lenInOut
       argument specifies the number of QChars that should be converted and is
       set to the number of characters returned.

       Reimplemented from QTextCodec.

const char * QHebrewCodec::mimeName () const [virtual]
       Returns the codec's mime name.

       Reimplemented from QTextCodec.
