David is right. Adrian Smith's APL385, based on Comic Sans, used to be the reference standard for cross-platform APLs using TrueType fonts. Most up-to-date monospaced fonts should have Lamp: '⍝' --e.g. AndaleMono (what I use on my iMac), Courier, FreeMono or Monaco.
If you're running an antique computer, like I am, be warned that fonts with the same names on Win and OS X often used to have different subsets of the utf-8 range, but I'm talking 5-10 years ago now. Worth downloading the latest version of these fonts, since I found once that a long series of OS X upgrades had not replaced my existing fonts -- at least, not all of them. All the usual APL chars (I say "usual" because historically any overstruck is a valid APL character) are in: U+2300-23FF (Miscellaneous technical). Lamp is U+235d (9053). What I'd do to verify the APL display capability of any computer platform is to go to http://code.jsoftware.com/wiki/User:Ian_Clark/APLChars …which shows the character table (⎕AV) of Dyalog APL version 12 in utf-8 plus a screen snapshot of what it ought to look like. It's then a question of finding which font your browser is using, or varying the font until the page shows true.
