I have seen that Meursault but it does not correspond the conventions in English school in the 1960s.
For example: I believe that K Y and Z were only used in words borrowed from Greek, eg Kalends or Zephyrus. I was used as a consonant and a vowel, Iulius and never Julius. U (written V in roman inscriptions) always existed as both a consonant and vowel but was written V in its consonantal form, eg Vesuvius.
X was always a vital component of the alphabet.
