You are right, "đ" can not be normalized, because it's not the combination of a letter with an accent, it's a letter by itself.

How should the character "đ" be replaced for you—by "d" or another letter?
@auvansang How should the character "đ" be replaced for you—by "d" or another letter?
Yes d is the correct letter
If "đ" was replaced by "d" it is theoretically possible (albeit not likely) to generate a duplicate slug.
For example if I hat a slug "mad" and generating a new slug the input was "mađ" then I'd have a collision: two "mad" slugs.
For some applications this might be totally irrelevant, because the URLs have a tipically numeric id before the slug, preventing address duplication.
So, the decision on how to replace "đ" depends on the context.
@juanlanus You would have this issue for pretty much anything. Used two spaces? Same slug. Used an accent? Same slug. Used an underscore and a space? Same slug
nice
Look seem that does not work for "đ" char
