One of the changes in PHP8.1 is that the functions that accept string arguments no longer accept null. For backward-compatibility we want to ensure that all functions in the core_text class do not show any debugging messages when we pass null.

|
deprecated. This matches the behavior of user-defined functions, where null
|
is never accepted by non-nullable arguments.
