Editing Rough breathing (section)

==Technical notes==
In [[Unicode]], the [[code point]] assigned to the rough breathing is {{unichar|0314|COMBINING REVERSED COMMA ABOVE|cwith=}}. It is intended to be used in all alphabetic scripts (including Greek and Latin).

It was also used in the original Latin transcription of Armenian for example with {{unichar|0074|LATIN SMALL LETTER T}} in <big style="font-size:150%">t̔</big>.

The pair of space + combining rough breathing is {{unichar|02BD|MODIFIER LETTER REVERSED COMMA|cwith=◌}}. It may bind typographically with the letter encoded ''before'' it to its left, to create ligatures for example with {{unichar|0074|LATIN SMALL LETTER T}} in <big style="font-size:150%">tʽ</big>, and it is used for the modern Latin transcription of [[Armenian language|Armenian]] (which no longer uses the combining version).

It is also encoded for compatibility as {{unichar|1FFE|GREEK DASIA|cwith=◌}} mostly for usage in the Greek script, where it may be used ''before'' Greek capital letters to its right and aligned differently, e.g. with {{unichar|0391|GREEK CAPITAL LETTER ALPHA|cwith=&#x1FFE;}}, where the generic space+combining ''dasia'' should be used ''after'' the letter it modifies to its left (the space is inserted so that the dasia will be to the left instead of above that letter). Basically, U+1FFE was encoded for full roundtrip compatibility with legacy 8-bit encodings of the Greek script in documents where dasia was encoded before the Greek capital letter it modifies (it is then not appropriate for transliterating Armenian and Semitic scripts to the Latin script).

There is a polytonic Greek code range in Unicode, covering precomposite versions (i.e. breathing mark + vowel or rho, or vowel with pitch accent and/or iota subscript): Ἁ ἁ, Ἇ ἇ, ᾏ ᾇ, ᾉ ᾁ, Ἑ ἑ, Ἡ ἡ, Ἧ ἧ, ᾟ ᾗ, ᾙ ᾑ, Ἱ ἱ, Ἷ ἷ, Ὁ ὁ, Ῥ ῥ, Ὑ ὑ, Ὗ ὗ, Ὡ ὡ, Ὧ ὧ, ᾯ ᾧ, and ᾩ ᾡ.

The rough breathing was also used in the [[early Cyrillic alphabet]] when writing the [[Old Church Slavonic]] language. In this context it is encoded as Unicode {{unichar|0485|COMBINING CYRILLIC DASIA PNEUMATA}}

In Latin transcription of [[Semitic languages]], especially [[Arabic language|Arabic]] and [[Hebrew language|Hebrew]], either {{unichar|02BD|MODIFIER LETTER REVERSED COMMA}} or [[Modifier letter left half ring|a symbol similar to it]], {{unichar|02BF|MODIFIER LETTER LEFT HALF RING|cwith=◌}}, is used to represent the letter [[ayin]]. This left half ring may also be used for the Latin transcription of [[Armenian language|Armenian]] (though the Armenian aspiration is phonetically nearer to the Greek ''dasia'' than the Semitic ''ayin'').
