# https://raw.githubusercontent.com/ForkAwesome/Fork-Awesome/master/src/icons/icons.yml
# https://github.com/ForkAwesome/Fork-Awesome/blob/master/fonts/forkawesome-webfont.ttf
# 1.3 - Google Material Design

# 2 - Data sample
#
# Font Awesome example:
# - input: music:
# changes:
# - '1'
# - 5.0.0
# label: Music
# search:
# terms:
# - note
# - sound
# styles:
# - solid
# unicode: f001
# - output C++11: #define ICON_FA_MUSIC u8"\uf001"
# - output C89: #define ICON_FA_MUSIC "\xEF\x80\x81"
# - output C#: public const string Music = "\uf001";
#
# All fonts have computed min and max unicode fonts ICON_MIN and ICON_MAX
# - output C89, C++11: #define ICON_MIN_FA 0xf000
# #define ICON_MAX_FA 0xf2e0
# Exception for Font Awesome brands: we use ICON_MIN_FAB and ICON_MAX_FAB
# to differentiate between brand and non-brand icons so they can be used together
# (the defines must be unique in C and C++).
# - output C#: public const int IconMin = 0xf000;
# public const int IconMax = 0xf2e0;
