Transactions with tokens that have Chinese characters in their ticker are not imported properly - the token is simply ignored.
For exchanges of such tokens, only the cost and the deposit/withdrawal of the second token that is part of the exchange will be imported.
This is a huge problem as it forces users to go back and find every single transaction that could be affected, change the transaction type, get token amounts from the block explorer, etc. This is not feasible at all for high frequency traders.
Manually adding the correct token isn't possible either (searching for the contract address does not return results). The only way to represent those tokens is calling them NULL, which then forces the user to keep a separate lookup table in case of questions from the tax office.
Please fix this, it's a major issue. Competing products correctly import such transactions.
