I believe you have a basic misunderstanding of the nature of data within a
GIS.

Generally the way QGIS (and most GIS) works is they "take" only data such
as points lines and polygons and then the user develops styling on those to
create the desire cartographic effect.

It would be most unusual to find shading or text in a shapefile.

Test in a shapefile is an attribute of some geometric feature. So line 377
might have an attribute that is "Mid Atlantic Ridge".

QGIS provides the ability to print the text attributes as labels, which can
be styled in many useful ways for visualization purposes.


Everything I do find is rejected by QGIS as not being in a suitable format.
