Icons for categories

Category icons could improve the visual appearance and usability of this forum, especially once the migration introduces a much larger number of categories. Displaying flags for country-level categories was already mentioned as a possibility and would be a good example use case.

At the moment, we use Unicode characters/emojis to achieve a similar effect for some categories, such as “:lady_beetle: This forum issues and requests” and “:heavy_plus_sign: New category requests”. This is a decent approximation. However, this causes the symbol to be included even in contexts where a purely textural rendidion of the category title might be more appropriate.

Should we support this properly? There appears to be at least one relevant Discourse plugin:


I would be rather against more icons/emoticons.
