# # README | |
# | |
# In order for this theme to render correctly, you will need a | |
# [Powerline-patched font](https://github.com/Lokaltog/powerline-fonts). | |
# Make sure you have a recent version: the code points that Powerline | |
# uses changed in 2012, and older versions will display incorrectly, | |
# in confusing ways. | |
# | |
### Segment drawing | |
# A few utility functions to make it easy and re-usable to draw segmented prompts | |

# NOTE: This segment separator character is correct. In 2012, Powerline changed | |
# the code points they use for their special characters. This is the new code point. | |
# If this is not working for you, you probably have an old version of the | |
# Powerline-patched fonts installed. Download and install the new version. | |
# Do not submit PRs to change this unless you have reviewed the Powerline code point | |
# history and have new information. | |
# This is defined using a Unicode escape sequence so it is unambiguously readable, regardless of | |
# what font the user is viewing this source code in. Do not replace the | |
# escape sequence with a single literal character. | |
# Do not change this! Do not make it '\u2b80'; that is the old, wrong code point. | |
