@hadley what are you expecting as input and output? For now, I have the following but not sure this is what you need.

> has_glyph( c( "\u265E", letters, "valid", "invalid \u265E"), bold = TRUE, italic = FALSE, fontname = "sans")
 [1] FALSE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE
[15]  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE  TRUE
[29] FALSE
