Scintilla supports many features to make code editing easier in addition to syntax highlighting.

The basic regular expression search implementation is rudimentary, but if compiled with C++11 support Scintilla can support the runtime's regular expression engine.

Scintilla's regular expression library can also be replaced or avoided with direct buffer access.

[4] Scinterm is a version of Scintilla for the curses text user interface.

Scinterm uses Unicode characters to support some of Scintilla's graphically oriented features, but some Scintilla features are missing because of the terminal environment's constraints.
