Our test case relies on the outcome of the family property from freetype though,
it was changed in 2.7.1:
- PCF family names are made more `colourful'; they now include the
foundry and information whether they contain wide characters.
For example, you no longer get `Fixed' but rather `Sony Fixed'
or `Misc Fixed Wide'.
