• sz to ß
• Virgel to comma
• Quotation marks are transferred to today's use and are not differentiated
• Separators are transferred to today's use and are not differentiated
• the round-r in connection with c ist dissolved to etc.
• The reproduction of spaces is limited to the separation of words.
• Punctuation marks are always used in conjunction with the preceding word.
