Why unicode word is not matching but english word will match with my regex

Hi i’m trying to match the any give word if

1. if it begins with (same letters)
2. exact match (exact word)

My regex is something like this

/(?<=[(["]\s*|\b)(टीम\w*|UAE\w*|afri\w*)(?=\b|\s*[\])"])/igm

which works for english words but fails with hindi words

Note: my expectation is to match both english and hindi

Here is what i have tried Regex101.com

Problem: my pattern is matching english words perfectly but not matching this hindi word टीम

>Solution :

I managed to come up with something:

(?<=[(["\s]|^)(टीम|UAE|afri)[^\]\s)"]*

Please tell me if there are cases missed.
