# Ideally the raw characters should align with the braille dots.
#
# On most systems, it seems that Windows will fall back to using "Segoe UI Symbol" font.
# The width of BRAILLE_SPACE_CHARACTER ('no pins up') does not match the other braille characters.
# This causes variations in the length of the braille text, particularly when the cursor is flashing.
# The other disadvantage of using this font is that it is difficult to get its width to match the width
# of the raw text characters.
# These issues are solved by using a custom font (FreeMono-FixedBraille), which due to its free (GPL 3)
# status, allowed us to modify it, and fix the visual issues that it also had.
#
# Remaining visual issues:
# Some words when translated to braille have more characters than the raw text.
# This may be because there is a leading "number" or "capital letter" cell.
# Currently we do not handle this.
