[fpc-pascal] Unicode function names

[Mark Morgan Lloyd]

Out of curiosity, I've just tried creating a function named ⍳ (Unicode 
character 2373, i.e. the APL iota function). FPC trunk complains

Fatal: illegal character "'�'" ($E2)

What is the rule here- functions must be entirely ANSI or functions must 
start with ANSI?
