I'm struggling with Unicode support on a Wiki that is fairly current, but originated ~15 years ago. Before I just start fresh and import a page dump, I wonder if some of the maintenance scripts could help. I've routinely run doMaintenance when upgrading. I noticed update titles for Unicode and wonder if there are more that could help. I couldn't find documentation on the Media Wiki website around what code page flag to use. MySql seems to be moving to UTF-32, but wonder if that's best for Media Wiki software.
Some software versions:
OS: Windows 10 desktop - recently patched on release level versions.
Media Wiki 1.35.2
DB: MySQL 8.0.27
Web server: Apache 2.4
Edge browser v95
Eclipse for PHP developers 2021-03 is used for editing some files. It saves in cp1252. I do have some private extensions I maintain using this.
The specific problem I am seeing is that edits to wiki pages are rejected with the "browser doesn't support Unicode" error message. I've worked around for years by commenting out the Unicode check in Media Wiki source code for EditPage class, but would like to get at heart of issue. I just can't find it.
Appreciate any guidance.
