Changing Line Combination Character in Paragraph

[akkyie]

First of all, thanks a lot for your great work!

This time, I want to change the character which used to combine lines in paragraph.
Concretely, this markdown:

This is

will be parsed into:

This is a markdown.

As you see a space was inserted, and this behavior is suitable for languages which use word dividers, but not for some languages which doesn't use it such as Japanese or Chinese. So I want to remove this space.
I found that I can make it realized by changing '\n' to '' on the line 242 in Parsedown.php, but I don't want to tinker the original code.
Is there any solution without changing Parsedown.php itself but with extension?
Thanks

Just to confirm, you need

to become

This isa markdown.

Correct?

[akkyie]

Yes, exactly.

Something I would advise is opening this issue with the CommonMark spec, maybe a fix could be reached that could be applied to all parsers conforming to the spec in certain situations.
