Unicode encodes characters beyond the 128 ASCII symbols, so Chinese characters are represented by multi-byte sequences that ASCII cannot represent.

1) Relevant knowledge points and concepts
- ASCII is a 7-bit character set for basic English letters, digits and symbols (128 code points). It cannot represent Chinese characters.
- Unicode is a superset designed to represent characters from virtually all languages. Common encodings include UTF-8, UTF-16, etc.
- Encoding/decoding must match: text is converted to bytes with an encoding on send, and the receiver must decode those bytes with the same encoding. Email also uses headers (Content-Type: charset=..., Content-Transfer-Encoding) so clients know how to decode.

2) Step-by-step reasoning
- You typed Chinese characters. Your email client encoded those characters into bytes using a Unicode encoding (e.g., UTF-8).
- The message bytes were transmitted.
- Your friend’s email client attempted to decode the incoming bytes but assumed or only supported ASCII (or a 7-bit charset).
- Because ASCII maps only 0–127, any bytes with values outside that range cannot be interpreted as valid ASCII characters. The client either replaced them with placeholder/unprintable symbols or displayed garbled output (mojibake).

3) Intermediate example/calculation
- Example: the Chinese character 你 has Unicode code point U+4F60 and UTF-8 byte sequence E4 BD A0. If a client treats those bytes as ASCII, bytes E4, BD, A0 (values >127) are invalid in ASCII and will appear as garbled or replacement characters.

4) Why the correct answer is correct
- The observed symptom (Chinese becomes strange/unprintable) is a classic encoding mismatch: sender used Unicode (to represent Chinese), recipient only understands ASCII, so decoding fails. That exactly matches the chosen answer.

5) Why the other options are incorrect
- "Understands english": English is a language, not an encoding; clients interpret bytes via encodings (though English text often fits ASCII).
- "Sent ASCII, friend only understands Unicode": Unicode is a superset of ASCII, so a Unicode-capable client would display ASCII fine; this wouldn’t cause garbling.
- "Sent MIME, client did not understand MIME": MIME handles attachments and encoding wrappers; an unreadable charset mismatch is not primarily a MIME-format failure.
- "Sent binary, friend only understands text": vague and incorrect—email transports bytes; the issue is charset/encoding, not “binary vs text.”

6) Conclusion
The correct answer is: My email client sent the message in unicode, but my friends email client only understands ASCII. This matches the provided answer.
