Case converter
Retype nothing by hand. Identifier modes strip accents so the result can be a variable or a file name.

How it works
Upper, lower, sentence and title case keep accents. Identifier modes (camel, Pascal, snake, kebab, constant) remove accents and turn everything else into a separator. “Ação nova” becomes acaoNova in camel case.
Title case capitalizes every word, including short ones. It is a mechanical pass, not a newspaper style guide. Fix the small words after, if you need that voice.
Questions
Why does camel case drop the cedilla?
The identifier modes strip diacritics. Title case does not.
What is alternate case?
A visual effect that flips each letter. It is not a naming scheme.
Does sentence case understand Portuguese?
It capitalizes the first letter and letters after . ! or ?. It does not know about abbreviations.
