Some letters have the wrong fonts

[Cat-Robot]

Describe the bug
Some letters have the wrong fonts

To Reproduce
Select the following fonts, and type the alphabet

• Italic serif:
  𝑎𝑏𝑐𝑑𝑒𝑓𝑔 ℎ 𝑖𝑗𝑘𝑙𝑚𝑛𝑜𝑝𝑞𝑟𝑠𝑡𝑢𝑣𝑤𝑥𝑦𝑧
  The h does not have serifs, it's only italic. Comparing it with the one from Bold Italic Serif makes it even more obvious:
  𝒂𝒃𝒄𝒅𝒆𝒇𝒈 𝒉 𝒊𝒋𝒌𝒍𝒎𝒏𝒐𝒑𝒒𝒓𝒔𝒕𝒖𝒗𝒘𝒙𝒚𝒛

• Script:
  𝒶𝒷𝒸𝒹ℯ𝒻ℊ𝒽𝒾𝒿𝓀𝓁𝓂𝓃ℴ𝓅𝓆𝓇𝓈𝓉𝓊𝓋𝓌𝓍𝓎𝓏
  When I type then compare this g with the one from Bold Script, they look different, the one from Script looks like it's only italic
  𝓪𝓫𝓬𝓭𝓮𝓯𝓰𝓱𝓲𝓳𝓴𝓵𝓶𝓷𝓸𝓹𝓺𝓻𝓼𝓽𝓾𝓿𝔀𝔁𝔂𝔃
  But somehow the page preview doesn't show this mistake like other software do, so here's a picture
  

• Organic uppercase:
  ᗩᗷᑕᗪᗴᖴᘜᕼIᒍKᒪᗰᑎOᑭᑫᖇՏԎᑌᐯᗯ᙭Yᘔ
  the K and Y are not following the font, they are just uppercase K and Y.

• supertiny:
  ᵃᵇᶜᵈᵉᶠᵍʰᶦʲᵏˡᵐⁿᵒᵖᵠʳˢᵗᵘᵛʷˣʸᶻ
  ᴬᴮᶜᴰᴱᶠᴳᴴᴵᴶᴷᴸᴹᴺᴼᴾᵠᴿˢᵀᵁⱽᵂˣʸᶻ
  The letters c, f, q, s, v, x, y, z are only in lowercase and the q doesn't look right.

Expected behavior
The g from the Script font always looking the way it should just like the other letters do.
The wrong previously mentioned letters in the fonts remplaced with the right ones.

Android version
Android 8.0 "Oreo."

Thank you.
