I would like to colour the vowel ◌็อย of a given Thai word ผล็อย, part of which is the diacritic ◌็ on the consonant ล, without highlighting any of the consonant parts.
I have tried to do the following which should work based on Google searches but doesn’t colour the diacritic (everything else in the <span>
colours just fine): ผล<span class="highlight">็อย</span>
I have also tried inserting the COMBINING GRAPHEME JOINER (U+034F) before the <span>
which people online have mentioned helps the renderer to treat the base character and diacritic as separate pieces before formatting and combining, but this doesn’t seem to make a difference.
Lastly, I have tried turning off Unicode normalisation as per the manual and performing the above steps again with no success.
Is this a limitation of the Anki HTML renderer or is there something else going on?
