Character code according to ISO 10646 UCS-2 (not UTF-16).
<p>
All Closed Caption characters can be represented in Unicode, but unfortunately not all Teletext characters.
<p>
<a href="http://www.etsi.org">ETS 300 706 </a> Table 36 Latin National Subset Turkish, character 0x23 "Turkish currency symbol" is not representable in Unicode, thus translated to private code U+E800. I was unable to identify all Arabic glyphs in Table 44 and 45 Arabic G0 and G2, so for now these are mapped to private code U+E620 ... U+E67F and U+E720 ... U+E77F respectively. Table 47 G1 Block Mosaic is not representable in Unicode, translated to private code U+EE00 ... U+EE7F. That is, the contiguous form has bit 5 (0x20) set, the separate form cleared. Table 48 G3 "Smooth Mosaics and Line Drawing Set" is not representable in Unicode, translated to private code U+EF20 ... U+EF7F.
<p>
Teletext Level 2.5+ DRCS are represented by private code U+F000 ... U+F7FF. The 6 lsb select character 0x00 ... 0x3F from a DRCS plane, the 5 msb select DRCS plane 0 ... 31, see <a class="el" href="structvbi__page.html">vbi_page</a> for details.
<p>
<dl compact><dt><b><a class="el" href="bug.html#_bug000002">Bug: </a></b></dt><dd>
Some Teletext character sets contain complementary Latin characters. For example the Greek capital letters Alpha and Beta are re-used as Latin capital letter A and B, while a separate code exists for Latin capital letter C. libzvbi will not analyse the page contents, so Greek A and B are always translated to Greek Alpha and Beta, C to Latin C, even if they appear in a pure Latin character word. </dl> </td>
