<p> The QHebrewCodec class provides conversion to and from visually ordered Hebrew.
<p> Hebrew as a semitic language is written from right to left. As 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.
<p> Opposed 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 be 100%,
as reversing the bidi algorithm that transforms from logical to visual order is non trivial.
<p> Transformation from Unicode to visual Hebrew (8859-8) is done using the BiDi algorithm in Qt, and will
produce correct results, as long as you feed one paragraph of text to the codec at a time. Places where newlines
are supposed to start can be indicated by a newline character ('\n'). Please be aware, that these newline characters
change the reordering behaviour of the algorithm, as the BiDi reordering only takes place within one line of text, whereas
linebreaks are determined in visual order.
<p> Visually ordered Hebrew is still used quite often in some places, mainly in email communication (as most email programs still
don't understand logically ordered Hebrew) and on web pages. The use on web pages is strongly decreasing however,
as there are nowadays a few browsers available that correctly support logically ordered Hebrew.
<p> 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 8bit string.
<p>See also <a href="i18n.html">Internationalization with Qt</a>.

<h3 class=fn><a href="qcstring.html">QCString</a> <a name="fromUnicode"></a>QHebrewCodec::fromUnicode ( const <a href="qstring.html">QString</a> & uc, int & len_in_out ) const<tt> [virtual]</tt>
</h3>
Transforms the logically ordered <a href="qstring.html">QString</a>, <em>uc</em>, into a visually
ordered string in the 8859-8 encoding. Qt's BiDi algorithm is used to
perform this task. Please note, that newline characters affect the
reordering, as reordering is done on a line by line basis.
<p> You might get wrong results if you feed the string line by line to
this method, as the algorithm is designed to operate on a whole
paragraph of text at a time, and the contents of a previous line may
affect the reordering of the next line.
<p> To ensure you get correct results always call this method with
an entire paragraph of text to reorder.
<p> Some encodings (for example japanese or utf8) are multibye (so one
input character is mapped to two output characters). The <em>len_in_out</em>
argument specifies the number of QChars that should be converted and
is set to the number of characters returned.

<h3 class=fn>const char * <a name="mimeName"></a>QHebrewCodec::mimeName () const<tt> [virtual]</tt>
</h3>
Returns the codec's mime name.
