I tried numerous different fonts on J802 and found the dice characters displaying only with "Deja Vu Sans", "Deja Vu Sans Condensed", "Deja Vu Sans Mono", and "Unifont". I'm surprised that Courier and "Courier New" let me down. This is too bad because Unifont is the only fixed-width font that shows the dice and I don't really like the way it looks.
I'm also a little surprised that unicode does not give us very similar results across different systems. Interestingly, my jconsole under emacs seems to have no problem with the dice or the chess pieces which, as Pascal pointed out, could be rendered in proper starting position like this: 8 8$ u: 9800+(|.(8$23),20 22 21 18 19 21 22 20),(32$_9768),(8$17),14 16 15 13 12 15 16 14 On Wed, Dec 31, 2014 at 5:12 PM, robert therriault <bobtherria...@mac.com> wrote: > They work for me on j803 jhs with courier as the font. > > u: 9857 > ⚁ > > Cheers, bob > > On Dec 31, 2014, at 12:51 PM, Björn Helgason <gos...@gmail.com> wrote: > > > I use plain jqt on Android > > On 31 Dec 2014 20:12, "Skip Cave" <s...@caveconsulting.com> wrote: > > > >> The unicode characters 9856-9861 (hex 2680-2685) don't have the dice > >> characters on any of the fonts I tried in jqt64-j803 on my Win 8.1 > machine. > >> Any idea what fonts might have he dice characters? > >> > >> Skip > >> > >> > >> On Wed, Dec 31, 2014 at 6:24 AM, Björn Helgason <gos...@gmail.com> > wrote: > >> > >>> It all depends on what font is used. > >>> > >>> Many/most only have subsets of the pictures/fonts/bitmaps/signs for the > >>> unicode places. > >>> > >>> http://unicode-table.com/en/ > >>> > >>> press a sign and it will give a popup with the unicode number/name > >>> On 31 Dec 2014 11:25, "Linda Alvord" <lindaalv...@verizon.net> wrote: > >>> > >>>> u: 9856+i. 6 results in 6 empty boxes?
