Additionally, when written in capitals, "ß" is replaced with "ss" in Germany, whereas in Austria it is traditionally replaced with "sz" (the same digraph used in Hungarian for the "s" sound); there are some exceptions to these rules (see below).
Also, digraph diacritics are often used and sometimes even mixed with diacritical letters of standard orthography.
A phoneme may be represented by a multigraph (sequence of more than one grapheme), as the digraph sh represents a single sound in English (and sometimes a single grapheme may represent more than one phoneme, as with the Russian letter я ).
Because the first letter in a vowel digraph sometimes says its long vowel sound, as in sail, some phonics programs once taught that "when two vowels go walking, the first one does the talking."
In addition, there are also some runes which stand for a particular English digraph or diphthong.
Cryptonyms are sometimes written with a slash after the digraph, e.g., ZR/RIFLE, and sometimes in one sequence, e.g., ZRRIFLE.
