Follow-up Comment #11, bug #43907 (project octave):
What is the issue? Is it the warning message?
warning: ft_render: skipping missing glyph for character '2205'
I was assuming that there is simply no glyph in whatever font set is chosen
for character ' ', which I think means character 0. Typically those low
numbers are dodgy as far as glyphs, as ASCII alpha-numeric glyphs usually
start much higher in the code book. Why the code 2205 comes from ' ', I have
no idea.
ft_render means font render, which is in txt-eng-ft.cc.
FT_UInt
ft_render::process_character (FT_ULong code, FT_UInt previous)
{
FT_Face face = font.get_face ();
FT_UInt glyph_index = 0;
if (face)
{
glyph_index = FT_Get_Char_Index (face, code);
if (code != 'n'
&& (! glyph_index
|| FT_Load_Glyph (face, glyph_index, FT_LOAD_DEFAULT)))
{
glyph_index = 0;
gripe_missing_glyph (code);
}
else
Is that code related to OpenGL or just generic font rendering without
reference to the destination of the font usage? I don't see what the OpenGL
issue is. You'll have to explain further.
