UTF-8 bytes below were grouped by hand from RFC 3629. You can finish this card without running Python.

A code point is the integer that identifies a character. U+0041 means hex 41.
ASCII names the characters U+0000 through U+007F.
UTF-8 stores each of those as one byte equal to the code point.

A | U+0041 LATIN CAPITAL LETTER A | 41
é | U+00E9 LATIN SMALL LETTER E WITH ACUTE | c3 a9
€ | U+20AC EURO SIGN | e2 82 ac | three pairs

Guided activity: €! followed by LF (line feed).
Complete bytes: e2 82 ac 21 0a
Code points: 3 (€ then ! then LF)
Byte count: 5
The euro sign contributes three pairs; the other two entries contribute one each.

Accented-word reference for the later note.txt file, including one LF byte 0a:
Café
Code points, counting the newline: 5
Bytes: 43 61 66 c3 a9 0a
Byte count: 6
For a shorter pair list, count only the pairs that are actually present.

Optional, ungraded:
composed U+00E9 is c3 a9
decomposed U+0065 then U+0301 is 65 cc 81
A matching shape on screen is not matching bytes.
