To set these options use something like flags = 0 | TEXT_PRESERVE_LIGATURES | ....

one should not expect perfect conversions between every format and every other. Pandoc attempts to preserve the structural elements of a document, but not formatting details such as margin size. And some in the metadata subdirectory of the user data directory (see --data-dir). -p, --preserve-tabs[=true|false] Preserve tabs instead of converting them to spaces. (By default, pandoc converts tabs to spaces internally, the encoded value is used instead of the default specified by this option. --wrap=auto|none|preserve Determine how text is wrapped in the output (the source code, not the rendered version).

will move those nodes into that group. The moved nodes are collected into a group of their own to preserve their connection context, having their own group input and output nodes. The group’s existing input Cycle-Aware Keying When inserting keyframes into trivially cyclic curves, special handling is applied to preserve the cycle integrity (most useful while tweaking an established cycle): If a key insertion is attempted Merging vertices of course also deletes some edges and faces. But Blender will do everything it can to preserve edges and faces only partly involved in the reunion. Note At First and At Last depend on that
