Placeholder buggery?

[BendersRepublic]

Required
I need some help to provide you correct solution.

1. Tell me the detail about your problem.
   Upon joining, the hud is too low for viewing. But, if any reason, the servers placeholders are updated. It'll shift the hud up + remove other unicodes within my resourcepack, very confused. There's an attached video: https://streamable.com/963ceo

2. Upload some screenshot or text log related your issue. such as:

• Error log
• In-game screen (https://gyazo.com/188556c0bdc75660aa2db8403119467a)
• Your yml config (https://hastebin.com/share/ropisofufi.yaml)
• Your resource (Using the BodyHealth default hud)

3. Remember to notice your environment

• OS(windows/mac/etc)
• Server version(1.21.1/etc) (1.21.1)
• Server platform(spigot/paper/folia/fabric/etc) (Paper: 128-main@7e21cb8)

Disclaimer
I do NOT provide any solution to that.

• Using informal launcher such as Feather client (no, testing with vanilla, and another test with optifine/shaders. same results)
• Closed-source plugin/mod such as Optifine and ItemsAdder (not applicable)
• Usage in hybrid bukkit such as ArcLight (No)

There are several possibilities of that issue.

• Unsupported language found
• External plugin's font(like emoji) found

okay, so to continue using my unicode + hud, what would be the solution?
