- *'maxcombine'* *'mco'* : Nvim counts maximum character sizes in bytes, not
  codepoints. This is guaranteed to be big enough to always fit all chars
  properly displayed in vim with 'maxcombine' set to 6.
  - You can still edit text with larger characters than fits in the screen
    buffer, you just can't see them. Use |g8| or |ga|. See |mbyte-combining|.
  - NOTE: the rexexp engine still has a hard-coded limit of considering
    6 composing chars only.
