These two succeed:

assert(equal(chomp("hello \u00E9", "\u00E9"), "hello "));
assert(equal(chomp("hello e\u0301", "e\u0301"), "hello "));

These two fail:

assert(equal(chomp("hello \u00E9", "e\u0301"), "hello "));
assert(equal(chomp("hello e\u0301", "\u00E9"), "hello "));

It's because chomp makes the erroneous assumption that if a string ends with
the delimiter, the code points match exactly.
