So: value #49 would represent a 1, value #90 a Z and so on. ![]() in the early days of computing, when computers were just glorified calculators, it was enough to have a 1:1 ratio between the byte possible values and the symbols one wanted to use, so ASCII was born (actually ASCII only "mapped" the first 127 values of the byte, but that is a detail).a byte can only be set to one of its 256 possible values,.computers write data to files in bytes,.Oversimplifying a bit, the story goes like this: So in essence: an error, you are trying to open maybe an MP3 or a JPG file believing it to be a 3MF instead.Īs for the "wrong encoding" option. The file is a binary one that is totally unrelated to 3MF.Solution: read on the rest of this answer. ![]() The file is a 3MF model but the character encoding in the file being different than the one your editor is expecting (typically Unicode/UTF-8, these days).Solution: try to see if common decompress utilities like zip, gzip, 7z can open the file. So for example the 3MF model has been zipped, and what you are trying to do is opening the zip archive in the text editor, rather than the file that is in the zip archive. ![]() The file is compressed but your machine can't detect it.
