Hi Bobby, In the Unicode Standard it says "In horizontal interlineation, the Bopomofo is generally placed above the corresponding Han character(s); tone marks, if present, appear at the end of each syllabic group of Bopomofo characters." Although I know that it is also possible to have the tone marks (except the 5th) appear above the bopomofo characters in horizontal ruby, this confirmed my expectation that the canonical order of the characters for plain text would see all tone marks appear after the syllable. It is important to standardise the order of code points to maximise the likelihood of matching and collation, etc. The actual position of the glyphs when displayed can be significantly different from the order in many scripts. I don't think we should determine the order of characters in storage according to the display in ruby scenarios if the order in non-ruby contexts is different - we should rely on the application to position things correctly (which it has to do for the other tone marks anyway). My question is really trying to get at what the general practice is for the 5th tone mark in zhuyin fuhao in all contexts, since I think that standardised ordering is more important than ease of display. Are you saying that people always, in all contexts, type the 5th tone mark before the syllable? I guess I should probably also check out the Unicode lists for information too.

If you were writing bopomofo out horizontally in plain text (i know that's not common), would you also put that tone marker before the syllable it refers to, or did you do so in the markup just so that the application would make it look right? >> >> Cheers, >> RI >> >> >> On 07/03/2013 15:51, 董福興 Bobby Tung wrote: >>> Mr. Ishida >>> >>> Because this tone maker「˙」always appear on the top of Bopomofo, due to the pronunciation.
