apply_filters( 'relevanssi_default_punctuation_replacement', string $replacement )

$replacement
(string) The replacement value for punctuation, in practise an empty string or a space. Default value is space.

More information

The way Relevanssi handles punctuation by default is a list of replacements made based on Relevanssi settings and default values. These can be modified with the relevanssi_punctuation_filter hook.

Then the rest of the punctuation (anything that the regex [:punct:] catches) is replaced with the value this filter hook is applied to, by default a space. The space is generally a reasonable default value, in some cases it may be helpful to replace it with an empty string.
