[erlang-questions] How to detect \. in Markdown string

[lloyd@REDACTED]

Hello,
 
Daring Fireballs Markdown specification notes :
"1986. What a great season.
In other words, a number-period-space sequence at the beginning of a line. To avoid this, you can backslash-escape the period:
1986\. What a great season."

https://daringfireball.net/projects/markdown/syntax#block

But darned if I can find an Erlang function to distinguish these two cases:

2> S = "1986\. What a great season.".
"1986. What a great season."
3> 
3> string:chr(S, "\.").
** exception error: no function clause matching string:chr("1986. What a great season.",".") (string.erl, line 97)
4> string:chr(S, "$\.").
** exception error: no function clause matching string:chr("1986. What a great season.","$.") (string.erl, line 97)
Yada yada

Indeed it looks like the escape character isn't even represented in the string.

Can anyone please show me the way?

Best wishes,

LRP
