Title underlining (i.e. ====) seems unreliable

[Shungy]

You need to have the same or more number of = signs under the title otherwise it doesn't detect it. This might be expected behaviour, however some unicode characters seem to count as multiple chars. So the following will be interpreted as a paragraph:

test †
======

To make it interpreted as a level one header it needs two more equal signs:

test †
========

I think if you don't take the number of chars in the title into the account and just assume any line on top of 3 or more equal signs as a level one header it would be more reliable and give you the expected output every time.

Just FYI, if you change the following line:

smu/smu.c

Line 561 in 2a8d5b1

if(j >= l) {

To for example:

if (j == l || (p[j] == '\n' && j > 3)) {

It will work. Other Markdown parsers handle it this way too. Tested with "discount" and "lowdown".

It will work.

Nope, it will fail on this example:

ábc
===

I think the best would be to simply use

if(j >= 3) {
