Erro on alphabetical pagination (4.0.13) for categories

[RobertG]

Hi,

I've just noticed an error in the display of the list of books by category when alphabetical pagination is enabled.
The list of categories displays correctly, but when I click on a category, I get the error 0:
Too few arguments to function HTMLIcon::alphabet(), 0 passed in /home/*******/Sites/livres/components/com_abook/views/category/tmpl/default_items.php on line 105 and exactly 1 expected
PHP version is 8.4
