Description
Describe the bug
Capitalizing the German letter ß gives SS instead of ẞ.
To Reproduce
Steps to reproduce the behavior:
- Type any text that contains ß. (For example, Gauß und Weierstraß.)
- Select the text.
- Press
gU. - Gauß und Weierstraß is converted to GAUSS UND WEIERSTRASS.
Expected behavior
Since there is already the uppercase version of ß (https://glyphsapp.com/learn/localize-your-font-german-capital-sharp-s), I expect the result to be GAUẞ UND WEIERSTRAẞ.

Research direction
Start by reproducing the gU operation in VSCodeVim using text containing ß, then trace the visual-mode capitalization handling. Done means capitalization produces ẞ rather than SS for German sharp S, while preserving the existing behavior for other text.
