These settings predate the ubiquity of UTF-8, which did not begin to
see widespread adoption until the mid-to-late 2000s, and did not reach
ubiquity until the mid-2010s:

mbstring.script_encoding was introduced with this commit and released
in PHP 4.3 (renamed to zend.script_encoding in PHP 5.4):
https://github.com/php/php-src/commit/f30b722f14521fbad2fabe5fdcaa2b60fe97e=

zend.detect_unicode introduced in this commit, released with PHP 5.1:
https://github.com/php/php-src/commit/a8c6b992b8894763c59276c1142971aa9a314=
500

zend.multibyte introduced with this commit, released with PHP 5.4:
https://github.com/php/php-src/commit/ab93d8c621645e05d6a6a431d52ac64eda956=
673

declare(encoding) appears to predate all of the PHP 4.0 tagged
releases, including the pre-release ones.
