I think its better to use lit_compare_utf8_string_and_magic_string to compare with "Infinity", the code would be more compact:

if (lit_compare_utf8_string_and_magic_string (iter.buf_p + start.offset,
                                              iter.buf_size - start.offset,
                                              LIT_MAGIC_STRING_INFINITY_UL))
{
  ...
}

We can't use lit_compare_utf8_string_and_magic_string here, because we have to check if a prefix of the string contains "Infinity". For example, "Infinityfoo" should also be valid.

OK, I see.

Thanks for the tests,

Could you, please, replace lit_utf8_iterato_read_prev with lit_utf8_iterator_decr when you don't use return value?

[dbatyai]

Fixed.

LGTM.
