All else as predicted from the above, or in the case of katakana extensions, the obvious phonetic meaning for which the sequence exists in the first place.
Katakana and hiragana are treated exactly the same.
The long vowel mark is considered a reiteration of the core vowel of the previous mora, or in the case of ん, an extension of that sound.
