The UTC accepts documents from any organization or individual, whether they are members of the Unicode Consortium or not.
The UTC holds its meetings behind closed doors. As of July 2020, the UTC rules on both emoji and script proposals at the same meeting.
Due to the
COVID-19 pandemic's effect on travel, the meetings, which used to be hosted on the campuses of various tech companies who would open their doors to the Consortium for free, were in 2020 held online via Zoom, although the discussions remain confidential. The UTC prefers to work by
consensus, but on particularly contentious issues, votes may be necessary.
After it meets, the UTC releases a public statement on each proposal it considered.
Due to the volume of incoming proposals, various subcommittees, such as the Script Ad Hoc Group and Emoji Subcommittee, exist to submit recommendations to the full UTC ''

The UTC is under no obligation to heed these recommendations,
although in practice it usually does.
