latin characters

[fiubarc]

Hello, I have an issue when update a record with latin characters (ñ, á, é, í...)

db_codec='latin1'  is already set

For example, when read from db the record FERNANDO ÁLVAREZ is ok, but when update same data and then read it again, I get FERNANDO ÃLVAREZ

Python 3.7

Database MSSQL 2000

Web2py 2.18

Any ideas?

Thanks!
