I want to mention that notcurses library has its own approach to handle
unicode symbols and extended grapheme clusters in particular

https://github.com/dankamongmen/notcurses/blob/93a4890f4c2b491cda62fea5110995c6a25691e2/src/lib/egcpool.h#L98

Internally it uses libunistring

https://github.com/gnosis/libunistring

Hope this might be helpful
