you should be able to escape this behaviour by using "\\", e.g.
Markdown supports two styles of headers, Setext and atx.
Setext-style headers are “underlined” using equal signs (for first-level headers) and dashes (for second-level headers). For example:
This is an H1
This is an H2
Any number of underlining =’s or -’s will work.
Atx-style headers use 1-6 hash characters at the start of the line, corresponding to header levels 1-6. For example:
# This is an H1
## This is an H2
###### This is an H6
