{{Built-in|Atomic vector|⎕AV}} is the name of a 256-[[character]] [[vector]] which contains the entire character set of older APL implementations that did not support [[Unicode]], but instead used a single byte to store each character. Its value varies wildly between dialects, and can even differ between editions of the same dialect. | |||
[[Standards|ISO/IEC 13751:2001]] standard defined atomic vector as: "An implementation-defined character vector containing every member of the ''required character set'' exactly once".<ref>BS ISO/IEC 13751:2001: Information technology. Programming languages, their environments and system software interfaces. Programming language Extended APL. (2001).</ref> | |||

In order to maximise the probability of being able to represent the text when converting from Unicode to internal representation, [[APLX]] accepts as input a number of alternative Unicode values for certain characters. However, these are automatically mapped to normalised character, and any unmappable characters are replaced with a question mark. | |||
