# Roboto V2 Sources
This directory contains the current masters used to generate the Roboto Sans and
Roboto Condensed families.
### Updating Sources
When replacing the source VFBs, the source UFOs should be synced using FontLab's
vfb2ufo converter: http://blog.fontlab.com/font-utility/vfb2ufo/
Windows and Mac OS downloads are provided. The Windows download runs on Linux
wine [path-to-vfb2ufo]/exe/vfb2ufo.exe [roboto]/src/v2/Roboto_Thin.vfb
wine [path-to-vfb2ufo]/exe/vfb2ufo.exe [roboto]/src/v2/Roboto_Regular.vfb
wine [path-to-vfb2ufo]/exe/vfb2ufo.exe [roboto]/src/v2/Roboto_Bold.vfb
The converter should work both ways, so it is possible to convert altered UFOs
back into VFBs which can be opened in FontLab.
There is currently an issue when converting via vfb2ufo, in which
some anchors are dropped from glyphs. For now it is also necessary to run the
script `get_dropped_anchors.py` through FontLab after updating the VFBs, in
order to extract these dropped anchors into an external resource which is then
re-incorporated into the masters during the build.
vfb2ufo may output UFOs with bogus timestamps. Verify the openTypeNameCreated
field in the output `fontinfo.plist` files.
