Expected Results

The JIRA Service desk need to find items that are transferred to these words or labels in knowledge base Confluence.

Actual Results

JIRA service desk in customer portal don't find non-latin label name and content in knowledge base Confluence.

Notes

Note 1

JIRA service desk in customer portal don't find non-latin label name and content in knowledge base Confluence.
For example there is an article contains the text "test тест δοκιμή Prüfvorschrift specifikace спецификация není Latin", the fat in the confluence find only words consisting entirely of the Latin letters (spetsifikatse, test, Latin), and the words "тест δοκιμή Prüfvorschrift спецификация není" will not be found.

But search directly from the confluence is working properly, and all of the search words work.

Note 2

The search works with non-latin character when it is done from the request creation form.
