how can I fix my accent issues?

[Igniris Valdivia Baez]

hello, I have an ETL process collecting data from a postgresql
database and xls files and inserting in a postgresql database that
process occurs great in a local DB in postgres 14 with UTF8
codification and Spanish_Cuba.1952 collation but when I execute that
process in dev which is in postgres 15 and UTF8 with collation
en_US.utf8 the words with accents and ñ looks like an interrogation
symbol, what can I do to fix this?
thanks in advance
