+// "ABC AEY "

-// You can specify any encoding supported by htmlentities() as a second parameter
-echo StripAccents::strip("A strïng with àccénts", "iso-8859-1");
+echo StripAccents::stripNonPrint("ABC ÀÈÝ 是我这", replaceWith: "-");
+// "ABC AEY ---"


The example output for stripNonPrint(..., replaceWith: "-") appears incorrect for the current implementation: the regex runs byte-wise (no /u modifier), so each 3-byte CJK character becomes 3 replacements (the tests assert 9 - total). Update the README example to match actual behavior, or clarify/document a character-wise replacement approach if that’s the intent.

The workflow is restricted to branches: [master]. If the default branch is main (as suggested by the PR diff base), CI won’t run for pushes/PRs to the default branch. Consider switching this filter to the actual default branch name or removing the branch filter to ensure CI runs on all PRs.

+        php-version: ['8.1', '8.2', '8.3', '8.4']


CI runs PHP 8.1/8.2, but the code in this PR uses typed class constants (PHP 8.3+). Either drop 8.1/8.2 from the matrix or adjust the code/composer constraints so the matrix matches the supported PHP versions.

Suggested change

php-version: ['8.1', '8.2', '8.3', '8.4']

php-version: ['8.3', '8.4']

+composer require codeinc/strip-accents
+```
+
+Requires PHP 8.1 or later.


README requirement statement is incomplete/inconsistent with composer.json: the package now requires ext-mbstring, but the README only mentions the PHP version. Also, if typed class constants remain, the minimum PHP version becomes 8.3+. Please align the README requirements with the actual composer/platform constraints.

Suggested change

Requires PHP 8.1 or later.

Requires PHP 8.3 or later with the `mbstring` extension enabled.

 class StripAccents
 {
-    public const DEFAULT_ENCODING = 'utf-8';
+    private const string DEFAULT_ENCODING = 'utf-8';


private const string DEFAULT_ENCODING uses typed class constants, which are not supported in PHP 8.1/8.2. With the current composer.json requirement (php >=8.1) and CI matrix including 8.1/8.2, this will cause a parse error on those versions. Either remove the constant type declarations, or bump the minimum PHP version (and update README/CI accordingly).

Suggested change

private const string DEFAULT_ENCODING = 'utf-8';

private const DEFAULT_ENCODING = 'utf-8';

-        'o', 'o', 'o', 'o', 'u', 'u', 'u', 'u', 'y', 'y'
+    private const array ACCENT_MAP = [


private const array ACCENT_MAP uses typed class constants, which are not supported in PHP 8.1/8.2. Since the PR targets PHP 8.1+ (and CI tests 8.1/8.2), this will make the test suite fail to even parse on those versions. Either remove the type from the constant or raise the project’s minimum PHP version and align CI/README.
