Re: All your QWERTY belong to us...
Spanish formerly treated CH as a separate letter, alphabetized between C and D: CZ < CH < D. (It's still a separate letter, but now officially collates as if it were C followed by H: CG < CH <CI...).
When I lived in San Juan (Puerto Rico), the city had a moderately large number of people with English surnames. In the phone book, Spanish names were alphabetized using the old Spanish collating rules, BUT English names used English rules. So you had Cabrera, Calderón, Cervantes, CHAMBERLAIN, CHRISTIE, Colón, Costa, Cruz, Cuellar, CHACÓN, CHÁVEZ, Dávila, Díaz.
