mutt: come visualizzare correttamente i personaggi emoji?

Mi piacerebbe riuscire a vedere correttamente i personaggi emoji in Mutt, ma ad esempio eg appare come ^ J nel cercapersone di Mutt. In esecuzione

:set pager=view

e riaprendo il messaggio visualizza correttamente il personaggio con vim.

L'email in questione è crittografata con PGP, ma penso che otterrei lo stesso con l'e-mail non crittografata ( https://groups.google.com/forum/#!topic/comp.mail.mutt/50_MpyYkXR4 ).

Ho anche trovato questo post ( /programming/23526353/how-to-get-ncurses-to-output-astral-plane-unicode-characters ), che spiega un possibile problema in cui mi imbatto, ma come ho detto vim mostra i caratteri nella stessa finestra del terminale. Inoltre sto usando glibc 2.19 e non vedo come queste due applicazioni potrebbero usare versioni glibc diverse sullo stesso sistema.

C'è un modo per ottenere il cercapersone integrato di mutt per visualizzarli correttamente?

EDIT: quindi ho dimenticato di includere qualcosa di completamente diverso da 'mutt' e 'vim' ... Sto eseguendo Debian stable con il pacchetto con patch mutt.

Mi aspettavo che l'email non elaborata fosse codificata in base64 (perché entrambi gli account sono gmail e il messaggio contiene caratteri non ASCII), ma è lo stesso. Sembra anche che nessun personaggio sia stato danneggiato durante il trasporto.

(Non mi aspetto che i miei commenti ricevano risposta da quando la domanda è stata pubblicata lo scorso maggio e l'utente non è più attivo da allora, ma potrebbe essere utile per gli altri.)

Assicurati di avere il set di caratteri del display nel tuo muttr impostato su "utf-8", come segue:

set charset = "utf-8"
