Line(2) has zero length and CatmullRom(7) is wrong (it self-intersects).

Here's a corrected version:

Point(1) = {0,0.0,0.0,0.1};
Point(2) = {4,0.0,0.0,0.1};
Point(3) = {0,1,0,0.1};
Point(4) = {-1,3,0,0.1};
Point(5) = {4,1,0,0.1};
Point(6) = {5,3,0,0.1};
Point(7) = {4.5,3.5,0,0.1};
Point(8) = {3.5,3,0,0.1};
Point(9) = {2.5,3.5,0,0.1};
Point(10) = {1.5,3,0,0.1};
Point(11) = {0.5,3.5,0,0.1};
Point(12) = {-0.5,3.3,0,0.1};
Line(1) = {2,1};
//Line(2) = {1,1};
CatmullRom(3) = {2,5,6};
CatmullRom(4) = {1,3,4};
CatmullRom(5) = {4,12,11,10,9,8,7,6};
Point(13) = {1,1.5,0,0.1};
Point(14) = {1,2,0,0.1};
Point(15) = {3.16028,1.3,0,0.1};
Delete {
   Point{15};
}
Point(15) = {2,1.3,0,0.1};
Point(16) = {1.75,1.75,0,0.1};
Delete {
   Point{16};
}
Point(16) = {2.3,1.75,0,0.1};
Point(17) = {2,2.3,0,0.1};
Line(6) = {13,14};
CatmullRom(7) = {13,15,16,17,14};
Line Loop(8) = {-7,6};
Plane Surface(9) = {8};
Line Loop(10) = {5,-3,1,4};
Plane Surface(11) = {10,8};
