Given a text and search query which could consist of multiple languages lets say polish and english, you need to find whether the given search query is substring of the input text or not.

There is an added condition, you are allowed to replace any substring with its corresponding meaning in other language. For example, given the following mapping:

ó - u
ł - ou
ż - zg

You can replace ó with u and vice versa, same for ł and ż

Following are some example inputs and output as per the above mentioned mapping.

Text | Term | Result soł | u | false soł | ou | true soł | ł | true sou | ł | true

Could anyone suggest some optimal solution for this problem.
