Algorand cannot recognize special characters

Hello. I haven’t received any useful response from my previous post. I would like to add a note in my transaction but it doesn’t recognize utf-8 characters. Only English characters are accepted. Are there way to encode my byte array so all the special characters will be correctly displayed? By the way, I write my app in go.
