如何找到下标字母表的unicode

看看维基百科的文章Unicode下标和上标。看起来这些字符分布在不同的范围内，并且并非所有字符都可用。

统一的Unicode标准用于剪切和粘贴为数字和公共定义完整的子脚本和超级脚本数学符号（⁰cco²³⁴ ⁵ ⁶ ⁷ ⁸ ⁹ ⁺ ⁻ ⁼ ⁽ ⁾ ₀ ₁ ₂ ₃ ₄ ₅ ₆ ₇ ₈₉ ₊ ₋ ₌ ₍ ₎ ),除q以外的全上标拉丁文小写字母(ᵃ ᵇ ᶜ ᵈ ᵉ ᶠ ᵍʰⁱᵏˡᵐ ⁿ ᵒ ᵖʳˢᵗ ᵘ ᵛʷᶻ ),有限的大写拉丁字母（ᴬ ᴮ ᴰ ᴱ ᴳ ᴴ ᴵ ᴶ ᴷ ᴸ ᴹ ᴺ ᴼ ᴾ ᴿ ᵀ ᵁ ⱽ ᵂ ),一一些带下标的小写字母（ₐ ₑ ₕ ᵢ ⱼ ₖ ₗ ₘ ₙ ₒ ₚ ᵣ ₛ ₜ ᵤ ᵥ ₓ)，和一些希腊字母（ᵅ ᵝ ᵞ ᵟ ᵋ ᶿ ᶥ ᶲ ᵠ ᵡ ᵦ ᵧ ᵨ ᵩ ᵪ ).请注意由于这些字形来自不同的范围，它们可能不属于大小和位置相同，具体取决于字体。

您可以从另一个答案中提到的维基百科页面复制characters。然后在python 中

characters = '⁰ ¹ ² ³ ⁴ ⁵ ⁶ ⁷ ⁸ ⁹ ⁺ ⁻ ⁼ ⁽ ⁾ ₀ ₁ ₂ ₃ ₄ ₅ ₆ ₇ ₈ ₉ ₊ ₋ ₌ ₍ ₎ ᵃ ᵇ ᶜ ᵈ ᵉ ᶠ ᵍ ʰ ⁱ ʲ ᵏ ˡ ᵐ ⁿ ᵒ ᵖ ʳ ˢ ᵗ ᵘ ᵛ ʷ ˣ ʸ ᶻ ᴬ ᴮ ᴰ ᴱ ᴳ ᴴ ᴵ ᴶ ᴷ ᴸ ᴹ ᴺ ᴼ ᴾ ᴿ ᵀ ᵁ ⱽ ᵂ ₐ ₑ ₕ ᵢ ⱼ ₖ ₗ ₘ ₙ ₒ ₚ ᵣ ₛ ₜ ᵤ ᵥ ₓ ᵅ ᵝ ᵞ ᵟ ᵋ ᶿ ᶥ ᶲ ᵠ ᵡ ᵦ ᵧ ᵨ ᵩ ᵪ'
for c in characters.split():
    print(c + '=' + hex(ord(c)))
