Teletext uses VERY old technology encoding in general. I don't know if it's true for other languages, but Hebrew teletext encodes the Hebrew letters using the 7-bit SI-960, which maps the Hebrew letters instead of the lowercase Latin letters (positions 0x60 to 0x7A). In Hebrew teletext you get the following unmodern practices:
1. 7-bit encoding, which allows only uppercase Latin letters to be used in the mixed Hebrew/English mode. Compare Russian KOI-7, Greek ELOT 927, which are like Hebrew SI-960 in mapping the non-Latin alphabet on top of the lowercase letters. 2. Teletext offers no bidirectional algorithm. The display mechanism is limited to monodirectional LTR, necessitating the use of visually encoded Hebrew (that is, monodirectional LTR written Hebrew; see also my Hebrew FAQ for a longer explanation). This needs to be inverted to logical order when converting to Unicode. -- Shlomi Tal שלומי טל _________________________________________________________________ Send and receive Hotmail on your mobile device: http://mobile.msn.com
