Ř
The grapheme Ř, ř (R with háček, example of Czech pronunciation: 
"řeka" ) is a letter used in alphabets of the Czech, Upper Sorbian, and Silesian languages. A similar consonant can also be found in some Norwegian dialects around Narvik and in Berber (especially in its Rif variety). However, of the official national languages, only Czech has it.
The Unicode glyphs are U+0158 Ř and U+0159 ř . Either can also be represented using the combining character U+030C ̌ COMBINING CARON.
Usage
In Czech it is used to denote [r̝], a raised alveolar non-sonorant trill. Its manner of articulation is similar to other alveolar trills but the tongue is raised; it is partially fricative. It is usually voiced, [r̝], but it also has a voiceless allophone [r̝̊] occurring in the vicinity of voiceless consonants or at the end of a word.
In Upper Sorbian, it denotes the voiceless postalveolar fricative [ʃ].
