Thank you for your leaving issue.
When define custom shapes, the string should follow svg format.
For example:
<svg viewBox="0 -5 100 100" x="0px" y="0px"><path fill="none" stroke="#000" stroke-width="8" d="M55.2785222,56.3408313 C51.3476874,61.3645942 45.2375557,64.5921788 38.3756345,64.5921788 C31.4568191,64.5921788 25.3023114,61.3108505 21.3754218,56.215501 C10.6371566,55.0276798 2.28426396,45.8997866 2.28426396,34.8156425 C2.28426396,27.0769445 6.35589452,20.2918241 12.4682429,16.4967409 C14.7287467,7.0339786 23.2203008,0 33.3502538,0 C38.667844,0 43.5339584,1.93827732 47.284264,5.14868458 C51.0345695,1.93827732 55.9006839,0 61.2182741,0 C73.0769771,0 82.6903553,9.6396345 82.6903553,21.5307263 C82.6903553,22.0787821 82.6699341,22.6220553 82.629813,23.1598225 C87.1459866,27.1069477 90,32.9175923 90,39.396648 C90,51.2877398 80.3866218,60.9273743 68.5279188,60.9273743 C63.5283115,60.9273743 58.9277995,59.2139774 55.2785222,56.3408313 L55.2785222,56.3408313 Z M4.79695431,82 C7.44623903,82 9.59390863,80.6668591 9.59390863,79.0223464 C9.59390863,77.3778337 7.44623903,76.0446927 4.79695431,76.0446927 C2.1476696,76.0446927 0,77.3778337 0,79.0223464 C0,80.6668591 2.1476696,82 4.79695431,82 Z M13.7055838,71.9217877 C18.4995275,71.9217877 22.3857868,69.4606044 22.3857868,66.424581 C22.3857868,63.3885576 18.4995275,60.9273743 13.7055838,60.9273743 C8.91163999,60.9273743 5.02538071,63.3885576 5.02538071,66.424581 C5.02538071,69.4606044 8.91163999,71.9217877 13.7055838,71.9217877 Z"></path></svg>

In terms of eraser feature, there is no feature to erase like windows common paint tool in my library.
Instead, you may delete objects(line, curve, image, shape, text etc) after selecting and pressing delete button.
