:content
Builds a conservative identifier by keeping ASCII letters, digits, and underscores and dropping other characters.

This is useful when turning user- or config-provided names into handler suffixes, DOM-safe variable stems, or CSS and JS hook names.


:example
print(ascii_safe_name("Hello, UCE!"), "\n");
