I'm not sure what this means. Does it mean that in vertical text where `tts:textCombine:all` is applied to the non-Japanese letters in the sequence 

お  ‎304A  HIRAGANA LETTER O
茶  ‎8336  [CJK Unified Ideographs]
は  ‎306F  HIRAGANA LETTER HA
t  ‎0074  LATIN SMALL LETTER T
e  ‎0065  LATIN SMALL LETTER E
́  ‎0301  COMBINING ACUTE ACCENT
で  ‎3067  HIRAGANA LETTER DE
す  ‎3059  HIRAGANA LETTER SU

the acute accent would be part of the horizontal text or not?
