12d Model utilises a lot of “text” based files, most of which can be edited either inside 12d Model or with a Text Editor. However, be aware that not all file formats are the same, and in particular the file encoding.
Whilst 12d has support for UTF encoded files, UTF does come in different flavours and not all are supported. And some Text Editors will change the UTF encoding to match it’s default settings.
Therefor, when editing text files it is best to do a Save As and check what encoding is being used. If it is any flavour of UTF, then it is best to change the Encoding: ANSI
When 12d accesses the text file, if needed the file encoding will be changed back to the relevant UTF format.
Below is an example of the Save As panel for Windows Notepad.
