They're stored in the file in "logical order", which is the order that the reader processes them when reading. That means, if he has an English document with some embedded Hebrew, then when he encounters the first Hebrew letter, his eyes will skip to the end of the Hebrew phrase (or the end of the same line if it's a multi-line hebrew phrase), and start working backwords until he hits the English, at which point his eyes will skip again across the Hebrew to the English text that follows the Hebrew. This is "logical order", and it's the order he reads in. It's also the order that a computer would use if it were: * lexicographically comparing mixed-language strings * performing text-to-speech conversion * rewrapping paragraphs * it is the order in which text is typed at the keyboard. See pages 19-20 of the Unicode Standard 5.0 (available online at http:// unicode.org/versions/Unicode5.0.0/ch02.pdf) Since display is the only part of the system that doesn't operate in logical order, it's logical to put the conversion into the display routines, rather than putting it into the file itself where it screws up every other operation the computer has to perform on it. --Ken -- Chanoch (Ken) Bloom.
