Strange japanese furigana ruby display (with test file)

[fxp33]

Hi to all,

I recently started a thread on the Sigil forum about vertical alignment of asian characters: https://www.mobileread.com/forums/sho...d.php?t=229255


I pushed my tests a bit further with furigana and ruby.

Funny enough, Calibre displays quite well ruby tags without any css. Nevertheless, the property ruby-position:after and before seem to be applied in a way that isn't clear to me yet.

The default, seem to be "after".
But when I explicitly insert a ruby-position instruction, it doesn't matter if the value is before or after, the furigana are displayed before...

You will find in the attached document a combination of css / no css, furigana / no furigana, vertical / no vertical, processed / unprocessed ruby tags.

Beyond testing Calibre, the file could help check how e-readers deal with furigana and vertical alignment.

The file is simply edited in Sigil, and has not been modified by a Calibre import.

Japanese fonts can be found at : http://www.wazu.jp/gallery/Fonts_Japanese.html

And some information about ruby can be found at: http://www.w3.org/International/articles/ruby/ and here http://html5doctor.com/ruby-rt-rp-element/
(Hopefully, the source file I used isn't too far from the specifications).

Hope this helps

Regards,

François

Are you using the same font for text and ruby?
What are your line settings?

Hi,

@Kumabjorn: same fonts and just a style on rt tag:

style="max-width: 65px; text-indent: 1px; letter-spacing: 2px;"

The "problem" is that once the furigana are displayed before, and once they are displayed after... nevertheless, they appear and usually at the right place.
Even with the test using two rtc tags (second paragraph of each page).

Ohh, you mean that they appear either Before or after the Word they are attached to, instead of next to it? Are using tategaki or yokogaki?

Hi,

The file contains a combination:

• without furigana
• with furigana
  • horizontal yokogaki
    • with ruby css
      • with ruby-position:before
      • with ruby-position:after
    • without ruby css
  • vertical tategaki
    • with ruby css
      • with ruby-position:before
      • with ruby-position:after
    • without ruby css

etc.

Regards

I don't think you can mix tategaki and yokogaki in tree same text. I'd your problem likes to calibre's viewer? Because I know that calibre doesn't handle vertical text, Kovid Todd me that some time ago when I was looking at adding books from Sony Japanese site.
