I was happy to finally be able to write properly my language in PSO2 and not see black squares everywhere like in the Japanese client, until I sent the sentence and it completely disappeared, and after trimming it in parts I discovered the words with tildes were the culprit, and also special letters that are not ascii.
Can this be fixed? at least the Japanese client registers the log and you can always use a third party log reader, but now you can't even send the whole sentence unless you write in typos.
