There is always a terminating 0, even if the file ends in 0x1a.

http://dlang.org/lex.html, "End of File" shows this:
EndOfFile:
physical end of the file
\u0000
\u001A
Doesn't that mean that the input is empty if the file is empty, \u0000
or \u001A
is encountered?
Please follow the source code from file to input to the lexer.
Source as spec is no good. Either change the spec or admit that having
a tuple of sentinels as manifest constant is fine. In any case constant
tuples are easily unrolled into case statements.
