What negative effects can occur when converting a byte slice to a string?

Converting a byte slice ([]byte) to a string in Go can have the following negative aspects:

• Performance loss: the conversion creates a new string and copies data, which can be costly with large data volumes.
• Incorrect data interpretation: if the bytes do not represent a valid UTF-8 sequence, the string may contain invalid characters or replacements.
• Memory: strings in Go are immutable, so to modify data, new strings must be created, increasing memory usage.

Example:

b := []byte{0xff, 0xfe, 0xfd} // invalid UTF-8 sequence
s := string(b)
fmt.Println(s) // may output unpredictable characters or
