Try following the advice in several of the papers in jsoftware.com/papers :
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 . Cut&Paste to NotePad should work. If you select "Save As" and then choose the UTF-8 encoding, it'd preserve the APL chars. ----- Original Message ----- From: Raul Miller <[email protected]> Date: Wednesday, June 9, 2010 10:33 Subject: [Jchat] apl character support slowly improving To: Chat forum <[email protected]> > I noticed some apl on rosettacode: > > http://rosettacode.org/wiki/Luhn_test_of_credit_card_numbers#APL > > r←LuhnTest digits;even;odd;SumEven > (odd even)←↓⍉⍎¨{(n,2)⍴(⍵,'0')↑⍨2×n←⌈(⍴⍵)÷2}⌽digits > SumEven←{+/+/¨⍎¨¨⍕¨2×⍵} > r←'0'=⊃¯1↑⍕(+/odd)+(SumEven even) > > Unfortunately, when I tried copy and paste into notepad (and > into some > other contexts), the characters came out wrong. > > Also, when I tried searching for a symbol I did not recognize, > google gave me: > > Your search - ⍨ - did not match any documents. > > Which, to be fair, is the same thing I get when I try searching > for +.
