That is an error from your shell not kitty. Run cat first then paste and you will see kitty is pasting correctly.

I have the same issue with russian characters.

I copied a word from gedit into default gnome term and into the kitty term with Ctrl+Shift+V.

But when I write something in kitty term in russian and copy-paste this back it looks good, not escaped. And when I run vim inside kitty and paste in insert mode with Ctrl+Shift+V, then pasted text is escaped. But if I paste from register in normal mode ("+p), then everything is good.

Do not know where to dig.

This is not from the shell. The issue most likely comes from Firefox or Gnome/GTK.

If you copy from Firefox, it stores the actual unicode character under the clipboard targets UTF8_STRING and text/plain;charset=utf-8. The other targets (TEXT, STRING, etc) get its unicode escape, which is where kitty is reading the clipboard content from.

@emi2k01 Indeed, when I copy from Firefox to Kitty, it only gives the utf-8 codes, but when I copy from Kitty and paste into Kitty, I have the correct characters. The weird thing is that it used to work before, so I wonder what changed that made pasting from Firefox to Kitty not possible...
