The osmc:symbol tag provides a way to describe in a machine-readable way
route symbols in simple geometric shapes like they are found in some
European countries (and especially in Germany). The hiking map only
supports a subset of what is described on the Wiki page. In order to
be rendered on the map, the tag must have the following format:
osmc:symbol=waycolor:background:foreground:text:textcolor
waycolor must be there but is ignored for this map. foreground may not
be empty, a second foreground is not supported. text and textcolor can
be omitted. There is a
list of foreground and background symbols rendered in this map
available.
Note: the older version of the map accepted the foreground part to
be empty. This is no longer supported because the osmc:symbol tag
should only be used to describe geometric shapes. Without the foreground
shape, the symbol describes a simple reference of the way and, for the
sake of clarity will be rendered as such. Local exceptions may be possible.
