.ie n .IP "$bool = \s-1USE_GCS\s0" 4
.el .IP "\f(CW$bool\fR = \s-1USE_GCS\s0" 4
.IX Item "$bool = USE_GCS"
True if Unicode::GCString is installed.
.ie n .IP "$bool = \s-1USE_TERM_READKEY\s0" 4
.el .IP "\f(CW$bool\fR = \s-1USE_TERM_READKEY\s0" 4

.ie n .IP "$width = \fIterm_size()\fR" 4
.el .IP "\f(CW$width\fR = \fIterm_size()\fR" 4
.IX Item "$width = term_size()"
Get the width of the terminal.
.Sp
If the \f(CW$TABLE_TERM_SIZE\fR environment variable is set then that value will be
returned.
.Sp
This will default to 80 if there is no good way to get the size, or if the size
is unreasonably small.
.Sp
If Term::ReadKey is installed it will be used.
.ie n .IP "$width = uni_length($string)" 4
.el .IP "\f(CW$width\fR = uni_length($string)" 4
.IX Item "$width = uni_length($string)"
Get the width (in columns) of the specified string. When Unicode::GCString
is installed this will work on unicode strings, otherwise it will just use
\&\f(CW\*(C`length($string)\*(C'\fR.
