On the side, if of any help: 

I generally use ID's for linking to headings. 
The benefit is that headings can be re-named safley and links still work. 

There is an org-module called 'org-id', which when enabled in conjunction with the variable 
below allows you to automatically generate a unique id for the heading when you press C-c l and link to it with C-c C-l. 

This exports nicley also. E.g here is a unique anchor link to one of those unique ID's:

Subject: [O] Internal Links with Spaces 

Hi List, 

I'd like to re-raise the issue discussed here . In short, storing and inserting an internal link to a headline containing spaces using org-store-link and org-insert-link causes export to fail because the space is "hexified" into %20. 

It seems like the thread died because hexifying links to support external URL's conflicted with internal links containing spaces with no clear path forward. 

Am I missing further discussion where this was resolved? 

If not, is a fix still possible or is this a "won't fix" because of the clash with external links? 

If it's "won't fix", is it possible for me to advise org-insert-link (or some other function) or configure some other individual hack to work around the problem? I never use org-insert-link for URL's, so I'd be glad to blindly stop hexifying even if it breaks that functionality. 

Regards, 
Jake
