Import Wizard with Swedish charachters scrambles

Hello,

when using the import wizard for accounts (with the downloaded comma separated file) the French characters are OK but the Swedish charaters are ok until step 4 of the import (the example of the right):

in the csv, the example in step 3 etc all is well however.
in the step 4 the first line example changes to:
Skånevägen becomes SkÃ¥nevägen

I have tried tons of settings (Mariadb 10.1.20 / apache 2.4) among which
changing default char set in config.php to latin1 and swe7
adapting several types of 8859 in the csv and in the import wizard step 3 under File Encoding: (View Import File Properties)
changing char set database to latin1 / utf-8
changing char set client and connection to respectively utf-8, swe7, latin1

French characters such as Hervé are fine.

Tx for your help

FYI: show variables like ‘char%’;
