I've been trying to decipher the tone diacritics used in from jounralk page 157 onwards (page 10 onwards of https://kyoto-seas.org/pdf/7/2/070201.pdf). After massively increasing the magnification of the PDF, I see that three of them (numbers 6 'high-rise', 7 'low-rise' and 8 'high fall') are simply side-by-side combinations of U+0300 COMBINING GRAVE ACCENT 'low', U+0301 COMBINING ACUTE ACCENT, U+0302 COMBINING CIRCUMFLEX ACCENT 'fall' and U+030C COMBINING CARON 'rise'. Does this mean that they *are* encoded, but one 'simply' has to induce the renderer to choose to render them side-by-side rather than stacking them vertically?
I'm struggling with number 9 'low-fall', which sometimes resembles U+1AB0 COMBINING DOUBLED CIRCUMFLEX ACCENT, but may just be a pixellation effect for for side-by-side <U+0302, U+0300>. Number 4 'high-dip' could be U+0303 COMBINING TILDE. The other marks were easy to identify. Richard.
