FluentUI TextField type search support for foreign language

[thophan-microsoft]

Our team's codebase uses a TextField with type 'search' to filter list of multiple columns. We've noticed a localization behavior where even though the rest of the page, including the text in the columns (except for names), are localized to Chinese, but when we type in the TextField search box, it only filter if it's English, and won't filter if we type in Chinese characters. Is this expected behavior? Do we need to specifically add logic to filter by foreign languages?

No items in list displayed when 'Failed' in Chinese is typed in:

But does return items when English is typed in:

Can you provide a simplified repro case on StackBlitz?

I would expect any language to work in this scenario.

Thank you for confirming that it should work in this scenario without needing specific localization logic. We were able to narrow down the issue and fix it.

Root cause: The strings displayed in the UI are localized, but the search logic we have was comparing against the strings before they're localized.
