When I first looked at Pablo Impallari’s font Lobster around the end of 2011, it wasn’t yet capable of handling Pinyin with tone marks. But Lobster has improved since then.
A Pinyin-friendly bold condensed script font that looks good and is free — that’s great news.
It’s available through Google Fonts.
Unfortunately, its companion, Lobster Two, doesn’t have the same range and so cannot be used for Hanyu Pinyin with tone marks. But I’ll check again in a few years, just in case.
