Contemplate 2 methods of writing a 'dz' digraph dz - \u0064\u007a, 2 basic latin block codepoints DZ - \u0044\u005a Dz - \u0044\u007a dz - \u01f3, lowercase, single codepoint DZ - \u01f1, uppercase Dz - \u01f2, TITLECASE! What happens if you try to express dż or dź from polish orthography? You can use dż - \u0064\u017c - d followed by 'LATIN SMALL LETTER Z WITH DOT ABOVE' dż - \u0064\u007a\u0307 - d followed by z, followed by combining diacritical dot above dż - \u01f3\u0307 - dz with combining diacritical dot above multiplied by uppercase and titlecase forms In polish orthography dz digraph is considered 2 letters, despite being only one sound (głoska). I'm not so sure about macedonian orthography, they might count it as one thing. Medieval ß is a letter/ligature that was created from ſʒ - that is a long s and a tailed z. In other words it is a form of 'sz' digraph. Contemporarily it is used only in german orthography. How long is ß? By some rules uppercasing ß yields SS or SZ. Should uppercasing or titlecasing operations change length of a string?
