Building fonts on OS X has name collision issue

[ghost]

Due to the glif default file naming scheme in Robofab glyphs like 'LJ' and 'Lj' are overwritten by one another. The UFO, OTF and TTF generated only have one of 'LJ' and 'Lj' or 'NJ' and 'Nj' instead of both in both pairs, or makeotf fails to produce them because of a key error.

We made a pull request to address the issue in robofab: robofab-developers/robofab#35
Another fix would be to use uninames for those glyphs.

I'm using macOS as well and have found this work-around:

• Using Disk Utility, create a new sparse disk image
• Because of a bug in Disk Utility on macOS 10.11, even if you select "case-sensitive" during creation, a case-_in_sensitive partition is created, so
• Select the new partition in the left sidebar of Disk Utility and select the "Erase" toolbar option
• Choose OS X Extended (Case-sensitive, Journaled)
• in your roboto directory, remove any out folder and ln -s /Volumes/my-disk-image out
• make in roboto dir

You can also build this with docker - here's the file I used:

FROM python:2.7

RUN mkdir /src
COPY . /src
WORKDIR /src

RUN pip install -r requirements.txt
RUN make

You can then docker build..., docker create..., and docker cp... the resulting files off the container as demonstrated in https://medium.com/@alexeiled/docker-pattern-the-build-container-b0d0e86ad601
