K with diagonal stroke (êÂÂ, êÂÂ) is a letter of the Latin alphabet, derived from K with the addition of a diagonal bar through the leg.
This letter is used in medieval texts as an abbreviation for kalendas, calends, as well as for karta and kartam, a document or writ. The same function could also be performed by "K with stroke" (êÂÂ, êÂÂ), or "K with stroke and diagonal stroke" (êÂÂ, ê ).
In the Breton language, this letter is used, mainly from the fifteenth to the twentieth century, to abbreviate Ker, a prefix used in place names, similar to the Welsh caer.
Capital and small K with diagonal stroke is encoded in Unicode as of version 5.1, at codepoints U+A742 and U+A743.
It may be transliterated as or as in the name of Emeline K/Bidi (), a French Réunion politician with a Breton surname.
