As the title suggests when you press Alt in the editor it underlines the English capital letters not the local ones. This is true in Arduino IDE 1.8.4 and 1.9

Research direction
First, identify the component responsible for drawing the menu bar or editor window where Alt triggers underlining. In the Arduino IDE (Java/Swing), this is likely handled by JMenu or custom UI. Search for 'mnemonic' or 'underline' in the codebase. The issue states that English capital letters are underlined even in localized versions, suggesting that the mnemonic key is set to the English letter rather than the localized character. Check the localization properties files (e.g., *.properties) for menu items and see how mnemonics are assigned. The fix may involve updating the mnemonic assignments to use the correct character for each locale. Alternatively, look at the code that sets mnemonics based on resource strings. Start by examining the 'processing' or 'app' source directories in the Arduino repository.
