Naming also differs between composite Unicode characters intended solely for APL (which match IBM naming) versus plain tacks also intended for other applications.<ref name="dickey"/> The documentation for Dyalog APL notes that the Unicode naming for composite tacks (and thus the IBM naming for all tacks), which follows the the lesser-used "Bosworth" convention,<ref name="dickey"/> runs contrary to convention in the APL community.{{refn|name=dyalogsheet}} |name=tacks}} ||
