C vs k
From Chezwiki
The use of C vs K in Latin transliteration is based on historical considerations in handwritten Chezian script.
The two alternate script forms of the Chezian letter caf, regular (C) and crossed (K), derive from scribal hands.
Caf is crossed when it occurs before ec (E) and y (I), and sometimes before /ut/ (when this derives from /ect/, written ec cta, in old Chezian).
In the old block letterforms, there is no alternate form of "caf".
