problem with name of mailboxes with special characters

[skym4n]

I made a migration from cPanel to Directadmin, everything working perfectly, except this issue of mailboxes with special characters.

mail_location = maildir:~/Maildir:UTF-8

I know I must configure the mail directory to support UTF-8, but where do I configure this? does anyone have the step by step?

the error only occurs in mailboxes that have special characters in the name.

solution
1-create file dovecot.conf in
/usr/local/directadmin/custombuild/custom/dovecot/dovecot.conf

2- change settings

mail_location = maildir:~/Maildir
for:
mail_location = maildir:~/Maildir:UTF-8

add line:
maildir_broken_filename_sizes=yes

3 -next step:
cd /usr/local/directadmin/custombuild;
./build dovecot_conf;
