When the Joint Technical Committee, ISO/IEC JTC 1, was established in 1987 as a merger between ISO/TC 97, Information Technology, and IEC/TC 83, the subcommittee was transferred into JTC 1, becoming ISO/IEC JTC 1/SC 2. Certain standards that are now under the jurisdiction of the ISO/IEC JTC 1/SC 2, such as ISO/IEC 646, were published before the creation of ISO/IEC JTC 1, under ISO/TC 97. The original working groups (WGs) of ISO/IEC JTC 1/SC 2 were:

The subcommittee was established in 1987 under ISO/TC 97 as ISO/TC 97/SC 2, originally with the title "Character Sets and Information Coding", with the area of work being, "the standardization of bit and byte coded representation of information for interchange including among others, sets of graphic

The discontinuation of ISO/IEC JTC 1/SC 2/OWG-SORT was unanimously approved by resolution at the 2014 plenary meeting of ISO/IEC JTC 1/SC 2. The project, ISO/IEC 14651, which was allocated to ISO/IEC JTC 1/SC 2/OWG-SORT is now handled directly under ISO/IEC JTC 1/SC 2.

ISO/IEC JTC 1/SC 2 works in close collaboration with a number of other organizations or subcommittees, both internal and external to ISO or IEC. Organizations internal to ISO or IEC that collaborate with or are in liaison to ISO/IEC JTC 1/SC 2 include:

Standards under development within ISO/IEC JTC 1/SC 2 include amendments to the ISO/IEC 10646 standard (covered by ISO/IEC JTC 1/SC 2/WG 2) and amendments to the ISO/IEC 14651 standard (covered directly by ISO/IEC JTC 1/SC 2 rather than in a WG).

P-members are obliged to respond to ballots on standards developed by SC 2 (although they can enter an "abstain" response to a ballot if they choose to do so). O-members may comment on ballots, but are not allowed to vote.

ISO/IEC JTC 1/SC 2 has one active working group (WG), which maintains the standard for the Universal Coded Character Set (ISO/IEC 10646). The focus of this WG is described in the group's terms of reference. That WG is:
