[steveluscher]

Add 0x0A here.

See anza-xyz/agave#7628.

solana-sdk/offchain-message/src/lib.rs

Lines 19 to 26 in 2cffbca

	pub fn is_printable_ascii(data: &[u8]) -> bool {
	for &char in data {
	if !(0x20..=0x7e).contains(&char) {
	return false;
	}
	}
	true
	}

Hey @steveluscher , I have pushed changes. Please check.

Thanks for this! There's some discussion right now about whether this requires a bump to version 1 of the schema, and what that version should include. See solana-foundation/SRFCs#3.
