Why are filenames containing some emojis renamed to Chinese characers?

I have a setup to transfer my files from my Windows machine to my Android phone via Syncthing. I notice that some files whose names have emojis are renamed to strange Chinese characters: - 🌒 C→ߌ⠃ - 🌓 C→ߌ㠃 - 🌔 T→ߌ䠔 - 🌕 N→ߌ堎 As the result in my phone they are write-protected. I'm unable to delete them:  However files whose name contains this emoji ✔️ are not affected. Not sure if this is relevant to the problem, but for full information, when I try to remove this protection, diskpart doesn't detect my Android phone.
