+# Non regression tests for issue: #150
+# -- How to turn off inline math highlights?
+
+# From: https://pandoc.org/MANUAL.html#math
+# Anything between two $ characters will be treated as TeX math. The opening $ must have a non-space character immediately to its right, while the closing $ must have a non-space character immediately to its left, and must not be followed immediately by a digit. Thus, $20,000 and $30,000 won’t parse as math. If for some reason you need to enclose text in literal $ characters, backslash-escape them and they won’t be treated as math delimiters.
