Filename encoding for special chars

[tlovenspclsauce]

To add clarity to what @onlythetoast and @Upgreydd said:

Edit /src/wiring/savePage.ts

1. Add the following on line 13. const path = require('path');
2. Remove line 94 and replace with

    const directoryPath = path.dirname(filePath);
    const fileName = encodeURIComponent(path.basename(filePath)); // Only encode the file name
    const fullPath = `file://${directoryPath}/${fileName}`;
    await browserPage.goto(fullPath);```
