In Unicode, 001B, 001D, 001C are defined as control characters, without defining their semantics and usage; see
http://unicode.org/versions/Unicode5.2.0/ch16.pdf

Are you sure that the keys actually send these codes? Names like "ESC", "GS", and "FS" that may be used in key caps do not necessarily imply that a particular code is generated.

Typically, for example, 001B is used in applications to create low-level "escape sequences", consisting of 001B (ESC) and a few normal characters, so that the escape sequence as a whole has some control function.

For some additional notes, check http://www.cs.tut.fi/~jkorpela/chars.html#control
