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.

It 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.
