This PR adds three SVG Icons. One to represent that an icon is not found - ICON_NOT_FOUND - so represent when an out-of-range value was used to specify an icon. The second - ICON_CHAR_NOTDEF - is to represent that a text character is not found in the specified font or font stack. The third - ICON_CHAR_REPLACEMENT - is to indicate the portion of a text string that contains invalid bytes. Pull Request: https://projects.blender.org/blender/blender/pulls/134008
