This should be really simple, but I can't figure it out. So: how do I get these two characters to merge up in a table?
〳 1st row, U+3033 VERTICAL KANA REPEAT MARK UPPER HALF
〵 2nd row, U+3035 VERTICAL KANA REPEAT MARK LOWER HALF
Those are used in the vertical writing of Japanese, and they're supposed to look like a big version of U+3031 VERTICAL KANA REPEAT MARK 〱 when combined. But simply setting border-spacing, padding, collapse etc isn't enough, since there's still space above and below the chars themselves. Failed attempt:
<table style='border-collapse:collapse'>
<tr><td>〳</td></tr>
<tr><td>〵</td></tr>
</table>
So how do I squeeze the juice out of the text? I suppose the ideal answer would be to use 'real' vertical writing capabilities in a browser, but as far as I can tell this is still a utopian draft.
