If the non-English text you are typing is Unicode safe, then yes, it'll work without any changes to the form or Collect.
Your MySQL DB will need to have utf8_unicode_ci because utf8_general_ci sorting is broken. Here's what my config looks like.
[mysqld]
character-set-server=utf8
collation-server=utf8_unicode_ci
max_allowed_packet=1073741824
I strongly recommend you try this setup first before rolling it out into production.
