There /are/ symbols that don't work reliably, but the basic arrow symbols seem to be pretty well supported. Okay I'll shift my position a bit... Arrows are likely present in a modern system font. Outside the Symbol font, they aren't a standard symbol in PostScript and the font standards are based on PostScript - OpenType being the latest though it has less PostScript than its predecessors. But fonts are still quite a different beast to Unicode. So fonts are completely free not to define arrows or most other symbols, however it seems that standard system fonts e.g Arial, Times New Roman on Windows define them. There's no guarantee they will be present in the standard system fonts on old systems or in non-system fonts that define whichever symbols the font designer feels necessary. Modern browsers might add in arrow from a different font if it is not present in the one chosen by the web page author - I suspect this is happening on this page where the arrow looks wrong typographically: http://conal.net/blog/posts/adding-numbers/ ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Notice that the font used in that page is fixed width. The arrow looks wrong because it has to fit in a fixed width space. Fixed width arrows all look stubby, even if they are styled like the rest of the font. Very few programming fonts have arrows or other symbols. When I played around with UnicodeSyntax, I tried lots of different fonts. The only one I found that is halfway readable is GNU Unifont (at unifoundry.com) ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

I thought I read that Firefox does a font swap if it can't find a glyph, but thinking about it myself I can't see that this would make sense - Firefox would have to know an awful lot about the OSes fonts to know if they have missing glyphs. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

dons: magnus: I know there's a .cabal file for the latest version of HP somewhere, but I can't coerce Google into finding me a link that actually works. Furthermore, the following page: http://hackage.haskell.org/platform/contents.html does list all the contents, but to my big surprise it doesn't link to the specific versions of the packages for HP, instead it links to the latest version found on Hackage. I'll generate a spec page from the .cabal file this week sometime.

Ah ha - indeed you are right and the puritans at W3C and Mozilla.org seem to have dug their heels in. Unfortunately arrows don't appear to be in either the Standard Latin Character Set or the Expert Character Set for fonts, so whilst they are clearly present in Unicode (U+2192 for right arrow seemingly) there's still no guarantee they are present in any given font. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Would someone with the power to make changes on the HP pages *please* make it as easy as possible to find the *exact* specification of what HP contains? Please, pretty please with sugar on top. No, a changelog entry (http://hackage.haskell.org/platform/changelog.html) is not very helpful (why the HP front page links to it I can't understand). Going via the Haskell wiki (http://www.haskell.org/haskellwiki/Haskell_Platform#What.27s_in_the_platform) to find a link to the .cabal (http://code.haskell.org/haskell-platform/haskell-platform.cabal) is not that user friendly. It's even worse that the latter link doesn't seem to work at all at the moment.
