Every sequence page ends with a table of the terminals this site has examined and whether each supports that sequence. This page gathers those tables into one: a row for each sequence, a column for each terminal. Yes means the terminal supports it, Partly that it supports some of it, and No that it does not; a blank cell means the terminal was not examined for that sequence. The sequence’s own page says why, in its notes.

The terminals were judged in different ways, as the sources page explains: the VT220, VT340 and VT510 by their manuals, libghostty-vt by what this site’s cases show when they run in it, Konsole by its source, ConEmu, iTerm2 and others by their documentation, and the terminals whose version says run in a VM or run as a library by running every case on this site in them.
