Mega Sign prefill field can't parse some characters and show question mark.

[Achates5F9E]

I am trying to send agreement with Mega Sign with dynamic company name and address. However, I found that for Werstern Eupope characters (ä, ö,ü, etc.), system can't parse it from CSV correctly. Instead, it will show it as a question mark, while for the rest is ok. How can I resolve the issue?

Let me move this to the Adobe Sign forum for you, which I hope is the appropriate forum for your question. If you're talking about a program called Mega Sign, you'll have to talk to their customer support.

The Using the Community forum is for help in using the Adobe Support Community forums, not for help with specific programs. Product questions should be posted in the associated product community.
