#69 without unicode 428 is as far as I can get.

[Esger]

<style>html{margin:95 135}{transform:matrix(var(--,.42,.42,-.42,.42,0,8));border-radius:50%50%0;background:#E08027;box-shadow:0 0 0 var(--s,5in)#191919}+{--:-1.19,1.19,-1.19,-1.19,-105,24;--s:0}>>{padding:57;--:0,1,-1,0,-108,0;--s:10px;--c:left;--b:81%0/45%100%}>{background:radial-gradient(16q at var(--c,top),#0000 6px,#E08027 0 15px,#0000)var(--b,0 81%/100%45%)no-repeat,radial-gradient(#191919 45px,#E08027 0

wow! matrix transformation being used!

[Esger]

Yeah, I used that for #63, #55 and #47 as well.

[gunnarbittersmann]

I’m using matrix on neither of these, but on #⁠25, #⁠34, and #⁠74.

[SelenIT]

I use it on #25 and #34, too. At some point, I used it on #21 as well, but later found shorter alternative without it.

Got to 318 without unicode so far:

<a><a><style>*+*{background:conic-gradient(from.8rad at 50%20%,#191919 75%,#E08027 0)0 43mm;margin:125 92}a+a{--:50%0;box-shadow:0 0 0 10px#191919}a{margin:-3;padding:48.5 57;border-radius:var(--,0)50%50%;background:radial-gradient(1q at bottom,#0000 6q,#E08027 0 5vh,#0000)0-54q,radial-gradient(1q,#191919,48q,#E08027

[SelenIT]

@gunnarbittersmann generously saved and shared previois iterations of Open Targets, the shortest non-unicode there is 304 char long (potentially 303 with .8rad instead of 45deg). Ironically, it seems non-optimal because of two pretty similar radial-gradients in one background, but all my attempts to reuse the same radial-gradient declaration (by moving the 2nd layer to a new HTML element) only made the code longer :)

Top solution gets 100% lol

As you can see in the bottom left corner of the page there is write: "HTML entities are rendered differently in different systems and might not work as you expect" So when you use unicode you should not check that from the CSS Battle site but I suggest you to check this previewer made by @Beowolve : https://tc70f3.csb.app/ .
