The byte sequence \357\277\275 (0xEFBFBD) corresponds to the unicode character 0xFFFD which is the REPLACEMENT CHARACTER (used to replace an unknown, unrecognized or unrepresentable character). Looking at the source-code, Wireshark uses this character when there was a problem reading a UTF-8 character (either because a multi-byte sequence was cut of in the middle or when a non-UTF-8 byte sequence was encountered).
Are you able to provide a capture file with this particular probe request? I would like to check whether there was a problem interpreting the SSID name or that there was indeed an invalid character in the SSID name.
