we've been using Roboto Light Italic as the typeface for Pinyin, which allows individuals who can't read Chinese to be able to pronounce the Chinese characters.

However, over the years, someone within our organisation has noticed that some of the Pinyin looked strange and weird whilst the rest of the Pinyin looked perfectly fine.

In this screenshot below, using a software application called ProPresenter, the glyphs have been set to Roboto Light Italic. However, some of the glyphs are not italicised at all and remain bold.

These glyphs are the vowels in Pinyin, (a, e, i, o and u).

Is it possible for you folks to have Roboto Light Italic support the following glyphs? ǎ ǐ ǒ ǔ

I replied,

Roboto is no longer maintained actively, the glyph set will not change. Our latest versions are Roboto Flex, which has a smaller glyph set, and Noto Sans, which has a larger glyph set; it seems both support these characters, although RF has a bug? If you confirm its buggy, we may be able to fix it there.

And they confirmed theǐ is broken:

Turns out that this character isn't encoded in the font, but is made by composing the character, and its Google Fonts API breaking the user experience, so closing.
