Pipeline to write non-English characters: is it possible without realm UTF-8 setting ?

I have a pipeline which copies address fields from one app to another. My - limited - experience shows that pipelines indeed can not write non-english caracters, only read them. So if in an address field contains any accented characters, it will not be copied, the old value stays in the destination. 

Now quickbase clearly states that pipelines can only read not write these characters if only my app and not the realm forces utf-8 (which is my case):

About UTF-8 Support

Is there some Jinja function  which can be of help here ? Or how to make a pipeline change its mind to handle the non-english characters as a workaround to the realm not-set to UTF-8 enforcing?

Thank You!
