Ownership transfer - description with non-ASCII chars cut short

[Jpja]

Transferred OLGA's issuance right with Dogewallet web.
Description changed from "Твои небесные черты" to "Твои небес"

It seems the bug relates to a wrong assumption that all characters take up one byte. Cyrillic characters take 2 bytes each.

"Твои небесные черты" is 19 char long; 17 cyrillic and 2 spaces. Takes up 17 * 2 + 2 = 36 bytes.
"Твои небес" is 10 char long; 9 cyrillc and 1 space. Takes up 9 * 2 + 1 = 19 bytes

Related issue for DogeWallet desktop - DogepartyXDP/dogewallet-desktop#4

Thank you for reporting this issue. I will look into this issue when I return from Costa Rica next week.

I did some testing on Counterparty testnet with Counterwallet (likely same issue with DP/CP and FW/CW).

Issued BJORN, entered title "Bjørn to be wild". Became "Bjørn to be wil". Then increased supply, title became "Bjørn to be wi". Transferred ownership, "Bjørn to be w".

One letter is cut off for every issuance due to the 'ø'.

I looked into actual op_return data here

Turns out every issuance transaction includes the title field. Behind the scene the wallet includes the title even if it's a supply increase or transfer. Therefore this bug appears for all issuances.

The exception is a 'LOCK' issuance because the title is literally set to LOCK. Counterparty in that case copies the previous title in the issuance table. So at least it's not an issue with Counterparty lib.
