 | 
						|
#                                 search:
 |

#                                 styles:
 |

#                                   - solid
 | 
						|
#                                 unicode: f001
 | 
						|
#           - output C++11:     #define ICON_FA_MUSIC u8"\uf001"

 | 
						|
#               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++).
