Is this related to Unicode surrogate is illegal in UTF-8?

Did you also read perlunitut and perlunifaq linked from Encode?

Question 1: Yes, perl can use a much larger set of characters than Unicode defines. See What's the difference between UTF 8 and utf8? and UTF 8 vs. utf8 vs. UTF8.

Question 2: This can be answered by reading the docs again:

If CHECK is 0, encoding and decoding replace any malformed character with a substitution character. When you encode, SUBCHAR is used.

(Emphasis mine)
