# General symbols
# For purposes of this table intended for general literary texts, some mathematical symbols and operators, such as + and % are considered as general symbols.
# This is because in Finnish braille, mathematical symbols are always preceded with space. Hence, if "+" was considered a mathematical symbol, expressions such as "my grade from the exam was B+" would be incorrectly translated to "B +". In table intended for mathematical textbooks, the preference would lean towards mathematical way of writing, and "+" would be considered a math symbol.
