Which Issue(s) This PR Fixes

Fixes #7702

Brief Description

When parsing the PPV2 protocol and setting the TLS contents as gRPC attributes, gRPC will log the following messages. To avoid excessive logging, filter out content that does not conform to ASCII.

How Did You Test This Change?

1. Open the ppv2 protocol
2. Send ppv2 message with tls data [61, 12, 109]
3. Check the log
