Inconsistent use of hyphens and old-fashioned spelling are left unchanged.
ന is used to represent a symbol described as “the Gothic M”. ⊏ and ⊐ are used to represent the primitive square-cornered forms of the Roman numeral Ⅽ and its reverse Ↄ.
₰ is used for the proofreader’s “dele” mark, which inexplicably still doesn’t have its own Unicode codepoint.
Characters which have no sufficiently close Unicode equivalent are included as illustrations.
