What are the chances of accidentally sending satoshis to an incorrect (but in use) BTC address, if a single character is mistyped in a Bech32 (SegWit) address?
I'm not sure about Bech32
-snip-For Bech32, there's a table in BIP-0173 containing the chances of certain number of wrong characters to create a valid SegWit address.

github.com/bitcoin/bips/blob/master/bip-0173.mediawiki#checksum-designIt looks complicated because its checksum isn't based from a few bytes from a hashed result.
@OP since you're asking about "
1 character"; based from the table above, there's zero chance that it'll be valid.
