The explicit specification of APL385 Unicode font on that page is to fix a worse display problem.
Anyway, I am not really interested in debating the fine points of rendering APL chars. I will not say more than what's in the fine print in http://www.jsoftware.com/papers/innerproduct/ip.htm (and other places). That fine print is: The text requires the APL385 Unicode font, which can be downloaded from http://www.vector.org.uk/resource/apl385.ttf . To resolve (or at least explain) problems with displaying APL characters see http://www.vector.org.uk/archive/display.htm . ----- Original Message ----- From: Raul Miller <[email protected]> Date: Tuesday, June 9, 2009 9:19 Subject: Re: [Jprogramming] Inner Product -- An Old/New Problem To: Programming forum <[email protected]> > I believe the problem with > http://www.jsoftware.com/papers/innerproduct/sparse1.htm > > is in <pre><font size=+3 face="APL385 Unicode"> > > If the face had not been specified, there would be no problem. > > Since the face was specified, you get some arbitrary default > browser font on machines without this font. > > The simplest cure would be to remove the face attribute, > but this might result in rendering inconsistencies between > pages. > > An alternative cure might be to specific an alternative font > face for browsers without APL385. > > Perhaps face="APL385 Unicode,Courier" > > Or perhaps something more elaborate... > > (Personally, I have had no problems with the rendering of > APL characters, and I do not have the APL385 font installed. > But I do not know what this means in terms of font faces.) ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
