This makes the directory to search for included files explicit.
Also use Python 3's FileNotFoundError to catch non-existant files instead of a workaround for Python 2.
Instead of copying to BytesIO, we can return the file name in getstate and reopen the file in setstate. This keeps the TTFont truly lazy as it avoids the extra copy
* when reading from binary, name.string may be an encoded bytes sequence: we should call toUnicode() before we compare to the requested string
* fix expected output
* Allow feature variations to be active across the entire space
* Add test with empty condition set
* Skip initial box instead of removing it
* Correct comment
[docs] Document cu2qu library
Reorganise the documentation so that everything is in one place and users are more clearly pointed to the modules which are likely to be useful for their purposes. (I still think it’s worth having at least a brief reference to ``cu2qu.cli`` in there, as a way of reminding users that there is a command-line implementation.) Docstrings are provided for non-API methods where I could understand them - trusting these will be useful for future maintainers.
https://tox.readthedocs.io/en/latest/config.html#conf-skip_missing_interpreters
Runing `tox` with no options runs the tests agaist all the python
environments listed in the `tox.ini`'s `envlist` (currently 3.6, 3.7 and 3.8).
Before this change, if any of these versions was not available, tox would exit with an error. Now it will simply continue (with a warning).
This can be useful when on a developer box, one might only have a subset of all our supported interpreters installed but we don’t want to mark the build as failed because of it.
Note that on the CI I am passing the opposite command line switch to override this setting, because there I want to make sure none of the specified interpreters is skipped.
Also, implement merging version 5 (by taking the min/max of the optical
point sizes), and rename `usMaxContex` to the correct name `usMaxContext`.
The typo was fixed in the OS/2 table some time ago, but we forgot to
also update the merge module.
Fixes#1865
