Capitalized Accented Characters no longer work with JQL (Select Custom Text Fields)

Environment

9.17.2+

Steps to Reproduce

1. Create a Select List (Single Choice) Custom Field.
2. Add at least one option with an Upper-Case Accented Character (É, Ô, etc...).
3. Create an Issue and use the custom field with the accented character selected.
4. Perform a JQL Advance Search for the Custom Field and Value.
5. Error Occurs:"The option 'XXXXX' for field 'YYYYYY' does not exist."

Expected Results

Issues with selected value to be listed, no error.

Actual Results

Error when using Upper-Case Accented Characters

Workaround

Please configure the same locale between Java (-Duser.language=en -Duser.region=US) and the database collation (en_US).

Notes

This does not occur when Lower-Case Accented Characters and this issue may be caused by recent changes (see JRASERVER-44588)
