The advent of '''[[wikipedia:Unicode|Unicode]]''' solved many problems with dealing with APL [[glyph|character]]s, however there was still some wiggle room as to which Unicode [[wikipedia:code point|codepoint]] were to be used in a Unicode implementation of APL, and different implementors made different choices. This article, which documents these differences, is adapted from an original paper by [[Bob Smith]]<ref>Smith, Bob. | The advent of '''[[wikipedia:Unicode|Unicode]]''' solved many problems with dealing with APL [[glyph|character]]s, however there was still some wiggle room as to which Unicode [[wikipedia:code point|codepoint]] were to be used in a Unicode implementation of APL, and different implementors made different choices.

Sudley Place Software.</ref> that attempted to raise awareness of these issues because the differences impede transfer of information. | ||
The relevant document for the APL character set is the ''APL Character Repertoire'' (ACR)<ref>ISO-IEC/JTC1/SC22/WG3. [http://std.dkuug.dk/jtc1/sc22/open/n3067.pdf N3067]: APL Character Repertoire. 28 Dec 1999.</ref>. For whatever reasons, that document never became a standard, but it does provide some guidance, and is better than each implementor making separate choices. | The relevant document for the APL character set is the ''APL Character Repertoire'' (ACR)<ref>ISO-IEC/JTC1/SC22/WG3.
