Report space as being a symbolic key rather than a Unicode codepoint.
+.TP
+.B TERMKEY_FLAG_CTRLC
+Disable the \fBSIGINT\fP behaviour of \fICtrl-C\fP. If this flag is provided, then \fICtrl-C\fP will be available as a normal keypress, rather than sending the process group a \fBSIGINT\fP. This flag only takes effect without \fBTERMKEY_FLAG_NOTERMIOS\fP; with it, none of the signal keys are disabled anyway.
.PP
When the constructor is invoked, it attempts to detect if the current locale is UTF-8 aware or not, and sets either the \fBTERMKEY_FLAG_UTF8\fP or \fBTERMKEY_FLAG_RAW\fP flag. One of these two bits will always be in effect. The current flags in effect can be obtained by \fBtermkey_get_flags\fP().
