============================================================================
Important: #98090 - Use preconfigured UTF-8 filesystem on first installation
============================================================================

See :issue:`98090`

Description
===========

Back in the old and dark days, some filesystems did not know about "special"
chars. TYPO3 has the :php:`TYPO3_CONF_VARS` toggle :php:`['SYS']['UTF8filesystem']`
to declare if filesystems are UTF-8 aware.

This toggle is :php:`false` by default since ever. It triggers functionality to
rename any file that contains characters like umlauts, or maybe entirely consist
of "special" chars only (japanese) to something "safe".

This is a usability issue since information is lost and language-specific
characters are destroyed.

Nowadays every serious filesystem supports UTF-8.

There are no issues related to UTF8filesystem=true for years.

The patch now sets UTF8filesystem=true for new installations to see if anything
still pops up. If that works out, we'll continue with further patches in v13 to
further phase out the option entirely.
