This page will list different uses of diacritical marks that have natlang precedence. Conlangers can use this to find inspiration for their own conlang romanizations.
Note that in this article combining diacritics are attached to a ◌. Diacritics without a ◌, like ¨ for example, are non-combining. Non-combining diacritics are sometimes called modifier letters in Unicode. The non-combining forms may for example be used when writing about a conlang's orthography, when one wants to refer to a diacritic without using any base letter with it.
When a letter is referred to without concerning about case, it is displayed like so: Ťť. This is for clarity's sake because some diacritics may look different depending on the letter's case.
