Sorry.  Here:

  (defun eglot-move-to-bytewise-column (column)
    "Move to COLUMN as computed using the LSP `utf-8' criterion."
    (let* ((bol (line-beginning-position))
	   (goal-byte (+ (position-bytes bol) column))
	   (eol (line-end-position)))
      (goto-char bol)
      (while (and (< (position-bytes (point)) goal-byte)
		  (< (point) eol))
	(if (>= (char-after) #x3fff80)  ; raw bytes take 2 bytes in the buffer
	    (setq goal-byte (1+ goal-byte)))
	(forward-char 1))))
