Re: [clreq] Where should tone marks be positioned when bopomofo appears over horizontal text? (#660)

Hello Richard,

> Normally, bopomofo annotations appear to the right side of each base Han character. However, in some cases, bopomofo can appear over horizontal text (much like pinyin). In those cases, are the non-neutral tone marks displayed after the bopomofo characters on the same line, or are they rendered above the other bopomofo characters?

Yes, according to the "[The Manual](https://language.moe.gov.tw/001/Upload/files/site_content/M0001/juyin/html_en/index.html)", when texts flow horizontally and bopomofo on upper side. Tone marks(2nd, 3rd, 4th tone) should always be on upper-right.

Normal fonts without any design for tone marks (ˊˇˋ）will display in this way.

Early Fonts from local foundry designed tone marks as full width glyph as figure above.
It's acceptable and if do so, better with alternative design with font feature switch to fulfill the requirement in the Manual.
