Loading .csv file in solr with separator as special-character

Enviornment - java version "11.0.12" 2021-07-20 LTS , solr-8.9.0

I am loading a csv file having separator Ǎ (decimal value- 461) in solr. For loading i have used following 2 ways.

1. curl "http://localhost:8983/solr/start13/update?commit=true&separator=Ǎ" --data-binary @/solr/python/special_character.csv -H 'Content-type:application/csv'
2. curl "http://localhost:8983/solr/start13/update?commit=true&separator=\Ǎ" --data-binary @/solr/python/special_character.csv -H 'Content-type:application/csv'

Both of the above command are leading to error as follows
