# Symbols (A0-BF)
#   JAWS and SuperNova have similar definitions.
#   BRLTTY[2] has many different definitions.
#   BRLTTY[1] has different definitions that are well explained.
#   Window-Eyes (based on descriptions) does not have all definitions.
#   liblouis does not have any definitions.
#
#   JAWS and SuperNova have the same definitions, except for A0, A1.
#   BRLTTY[2] has the same definitions,
#   except for A4, A6-A9, AD-AF, B3-B4, B6, B8, B9, BE.
#
# A number of conventions can be extracted:
#   * Inverted punctuation marks use the lowered literary form.
#   * Currency symbols use dots 46 with combinations of dots 78.
#   * Symbols resembling letters often use that letter,
#     either lowered or with dot 8.
#   * Accents use combinations of dots 456 with dot 8.
#   * Ordinal indicators use mirrored dots for the letters hj with dot 8.
#   * Quotation marks use dots for a more or less visual representation.
#   * Superscript digits use the letters abc with dot 8.
#   * Fractions use the letters uvx with dot 8.
#
# Use the definitions from JAWS and SuperNova for this table.
# Exceptions:
#   * NO-BREAK SPACE (A0)
#     JAWS uses no dots.
#     SuperNova uses dot 7.
#     Use the definition from JAWS for this table.
#   * INVERTED EXCLAMATION MARK (A1)
#     JAWS uses dots 235, a literary exclamation mark,
#     which is also used for DIGIT SIX (36).
#     SuperNova uses dots 367, a lowered literary exclamation mark,
#     which is in line with INVERTED QUESTION MARK (BF).
#     Use the definition from SuperNova for this table.
#   * BROKEN BAR (A6)
#     JAWS and SuperNova use dots 158.
#     This is a good definition for EURO SIGN (20AC).
#     Instead, use dots 1578.
#   * NOT SIGN (AC)
#     JAWS and SuperNova use dots 25678.
#     This is a good definition for LATIN CAPITAL LETTER Y WITH DIAERESIS
#     (0178).
#     Instead, use dots 125678, the backslash with dot 8.
#     This leads to an exception for LATIN CAPITAL LETTER Y WITH DIAERESIS
#     (0178).

# Accented letters and symbols (C0-FF)
#   BRLTTY[2], JAWS, Window-Eyes and SuperNova have similar definitions.
#   BRLTTY[1] has different definitions that is well explained.
#   liblouis does not have any definitions.
#
#   JAWS and SuperNova have the same definitions,
#   except for C1, CD, D3, D8, DA, DD, F2, FD.
#   Window-Eyes (based on descriptions) has the same definitions
#   for E0-FF, except for E6, F4, F6,
#   has no definitions for E3, EC, F0, F5, F8, FC, FD,
#   and has many missing definitions for C0-DF.
#   BRLTTY[2] has the same definitions for E0-FF,
#   except for E3, F0, F2, F5, F8, FD-FF,
#   and has many different definitions for C0-DF.
#
# Two number of conventions can be extracted for small letters:
#   1) Letters with acute, diaeresis, grave or tilde, and eth and thorn
#      use dot 8 but not dot 7.
#      To transform from small to capital, lower the entire cell,
#      discarding dot 8.
#   2) Letters with cedilla, circumflex, ring above or stroke, and ae
#      use dots 78.
#      To transform from small to capital, remove dot 8.
#
# Use the definitions from JAWS, Window-Eyes and SuperNova for this table.
# If they differ, follow the appropriate convention as described above.
# Exceptions:
#   * LATIN CAPITAL LETTER A WITH TILDE, LATIN SMALL LETTER A WITH TILDE
#       (C3, E3)
#     JAWS and SuperNova follow convention (2) instead of (1).
#     This is most likely because using dots 18 (a with dot 8 for tilde)
#     and lowering the cell yields dot 2, which is DIGIT ONE (31).
#   * LATIN CAPITAL LETTER Y WITH ACUTE, LATIN SMALL LETTER Y WITH ACUTE
#       (DD, FD)
#     JAWS uses dots 1245678 for FD. This does not follow convention (1),
#     and can thus not be transformed into uppercase.
#     Following convention (2) also does not work,
#     because transforming yields RIGHT SQUARE BRACKET (5D).
#     On the other hand, this definition somewhat resembles the y (13456).
#     SuperNova uses dots 24568 for FD. This follows convention (1),
#     and can be transformed into uppercase.
#     Use the definitions from SuperNova for this table.

#
# A number of conventions can be extracted:
#   * Symbols resembling letters use that letter,

#   * Quotation marks use dots for a more or less visual representation.

# The definitions from SuperNova have a number of advantages:

#     Instead, use dots 25678, LATIN SMALL LETTER Y WITH DIAERESIS (FF)
