ggsave() to .html does not work with special characters

[gregorbaer]

🐛 Issue

Plots that are saved with ggsave() as .html cannot by default correctly display special characters (e.g. €, ü, ä, ö, etc.). This issue only occurs when saving to .html, not when saving to .svg or other formats, or when displaying the graphs in a notebook.

Manually editing the .html code of the saved plot to include the line <meta charset="UTF-8"> fixes the display issue.

💡 Proposed Solution

Use UTF-8 encoding by default when saving to .html with ggsave() (or another encoding which can deal with the special characters).
