EmEditor has a configuration to replace (or not) tabs with spaces for indenting (at beginning of line), but this is not my question. Even with this box unchecked, I observe that if I have text content with tabs mixed in (other than beginning of line), then edit and save the document, all tabs are replaced with spaces. How can I prevent this behavior? I suspect it is a configuration but I cannot find it. Version 20.4.4 on Windows 64 bit.
