migrate error: [CRITICAL] None 'ascii' codec can't decode byte 0xc2 in position 173: ordinal not in range(128)

I am sorry, but I have a new error when migrating another experiment of mine from cns60 to bsc32.

The exp is a5hn and my res user is cns60057.

Autosubmit version 3.14.0

Here the error I get:

autosubmit migrate a5hn -o
