Actually, your `mutt' mailer has managed to convert theUTF-8 encoding which I hope you received into ASCII andsubstituted its own `?' for those block characters whichshould have appeared as correct UTF-8, though I'll need tocheck an archive.
And after quite a few too many hours, I still don't get it,and I'm going to have to ask help from the collectiveknowledge pooled here.
I've seen that the 10646 encoded fonts available usuallyhave the familiar box-drawing and related characters I'vepartly been able to use for a few of the graphics.
Unfortunately, these seem to be either based on a 2x2 setof quads, or a 3x4 array. While the teletext graphics inuse uses a 2x3 array.
I've come upon two sets of fonts which supposedly coverthe teletext character set with a 10646 encoding. Butthe first one, which does include the 2x3 graphics charsthat otherwise need a `fontspecific' encoding, seems tohave hijacked existing assigned unicode characters inorder to display the graphics.
That is, with this font, these characters no longer displayproperly (selection limited due to pasting from a 512-charconsole font)[◆] U+25C6 ◆ BLACK DIAMOND[◊] U+25CA ◊ LOZENGEThis is matched by reading the code:const wchar_t graphutf8[128] = { // Graphic characters on an unicode terminal ISO-10646[...] 0x25A0,0x25A1,0x25A2,0x25A3,0x25A4,0x25A5,0x25A6,0x25A7, [...] 0x25B0,0x25B1,0x25B2,0x25B3,0x25B4,0x25B5,0x25B6,0x25B7, [...] 0x25C0,0x25C1,0x25C2,0x25c3,0x25C4,0x25C5,0x25C6,0x25C7, [...]0x25D8,0x25D9,0x25DA,0x25DB,0x25DC,0x25DD,0x25DE,0x25DF,};
I'm still trying to determine whether the second font has anygraphics and where they would be hidden -- even the handy[█] U+2588 █ FULL BLOCKcharacter is missing.
Does anyone know whether the various 2x3 graphics used inteletext fonts are in fact present in Unicode? I haven'tbeen able to convince google to give me the answer I want.I would think that with everything I do see with a unifontfont, that such widely-used characters wouldn't have beenleft out...
thanks for any pointers,barry bouwsma
