# UEB characters
#
# Some chars that originally came from an Excel spreadsheet, converted to csv, and the greatly expanded
# 
# The UEB translation makes use of some non-braille chars as flags
#    L -- what follows is a letter
#    N -- what follows is a digit
#    C -- precedes L for capital letters
#    G -- precedes L for Greek Letters (after C for capitals)
#  Typeface Indicators ("typeforms")
#    B bold, I Italic, S Sans-serif, T script, D, Fraktur, 𝔹 blackboard-bold
#    the type face indicators can be combined with B (first) and I (second)
#  Standing alone chars:
#    Any character which acts as a standing alone character (e.g, "{") needs each braille symbol to be labeled
#    o -- opening/left side, c -- closing/right side, b -- both open and close (e.g, '"')
