The %c format is only good for single-byte characters, which these
ones aren't. Please use %x to print them (in hex).
Also, I think printing everything is too much, and doesn't allow to
focus. Please print only when the character's code is one of those
involved in the problematic display. "C-u C-x =" will tell you the
codepoints of the characters involved: the one that is displayed
incorrectly and the ones surrounding it: please add an 'if' clause
there which would only print the metrics data for the characters in
which we are interested. Something like this:
if (chars[char_idx] == CHAR1
|| chars[char_idx] == CHAR2
|| chars[char_idx] == CHAR3)
printf (...
where CHAR1, CHAR2, and CHAR3 are the characters involved in the
problematic display, according to "C-u C-x =".
May I suggest that you show me the code you add to hbfont.c before you
run it? This would avoid unnecessary iterations for you.
Thanks.
