Accents enhancement for Pinyin typesetting
Describe the bug I plan to use Inter font to typeset Pinyin, the official romanization system of Mandarin Chinese. This is because Pinyin uses sans font and "single-storey letter a" out of habit, and I can easily do it by Inter's Opentype feature. Pinyin uses accents to denote different tones. In the screenshoots below, I have typeset all the possibilities of Pinyin letters with accents (in light, regular, and medium weight font). As you can see, some accents are not at the proper position.
Expected behavior For example:
- Accents of ǕǗǙǛ are inconsistent. Specifically, the diaeresis of ǕǗǙǛ have different height and weight. And the accents above diaeresis aren't at the same height either.
- The acute of ǘ seems too long.
- Ê/ê with macron/caron, M/m with grave, Ŋ/ŋ with acute/caron/grave, ə with tilde need adjustmment.

Environment
- OS: Windows 10
- LaTeX
- v3.19
Additional context ǕǗǙǛǘ need to be adjust first, for they have already been listed in Unicode table. For others, maybe need to edit the Opentype feature table later.

Progress update; how it's looking as of now:
Still a few marks/anchors missing: (for example Ŋ is missing a "top" anchor.)
