Uploading data with non-Roman characters

Hi all,

I'm wondering if anyone has a solve for importing data that doesn't use Roman characters? For example, accents on letters, Chinese characters. 

We are trying to import data from our Shopify account (where any character can be used) into Tessitura, which seems to only allow Roman characters. This is therefore requiring we either rewrite the data line-by-line to replace it with Roman characters, or we do not upload those records. 

I'm hesitant to restrict users to only using Roman characters in Shopify, as this data is used for international shipping of purchases etc. 

Would love anyone's thoughts, or to hear if anyone is having the same issue! 

Thank you!

Anna
