Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

     http://orgmode.org/manual/Feedback.html#Feedback

Your bug report will be posted to the Org-mode mailing list.
------------------------------------------------------------------------

I have an Org link as follows:

  [[message://m2k4n46n5p.wl%dave@boostpro.com]]

When I try to `C-c C-o' it, opening fails because the link-handling code
sees this string for the link:

  "m2k4n46n5p.wlÚve@boostpro.com"

which you may notice is different.  If I do 

   (org-open-link-from-string "message://m2k4n46n5p.wl%dave@boostpro.com")

on the other hand, it works just fine.

How did you enter the link into the Org file?

The original link

[[message://m2k4n46n5p.wl%dave@boostpro.com]]

Is unescaped, but Org treats links as always percent-escaped. What
happens is that "%da" is treated as a percent escaped character and
unescaped after read from buffer.

The link should read:

message://m2k4n46n5p.wl%25dave@boostpro.com

This is a troublesome situation

https://lists.gnu.org/archive/html/emacs-orgmode/2011-09/msg00257.html

But up to know I didn't find a solution for it.

Yeah, I finally figured that out.

Hmm, well, ... the link started out as a a wanderlust link of a form
more like this:

  [[wl:/message-id:"<m2k4n46n5p.wl%dave@boostpro.com>"/%%5BGmail%5D/All%20Mail#103387BF-79B8-4389-AD51-9550873479A1@gmail.com]]

_That_ link used to work.  I transformed links like that by
search/replace into:

  [[message://m2k4n46n5p.wl%dave@boostpro.com]]

So maybe it's my fault?

The original link is alread "wrong", i.e. unescaped.

The key question are

 1. How did you create the original link?
 2. When did you create the original link?

I tried taking a link with `org-store-link' and insert it with
`org-insert-link' and the link was properly escaped.

The link escaping was changed in November 2010, maybe the link in
question is an old one?

I used this code:
https://github.com/dabrahams/elisp/blob/master/elisp/autoload.d/wl-setup.el#L801
Is there some encoding step I should have applied?

It might have been as long as a year ago

Nope, the code should do the trick. The escaping is currently done
when the link is inserted via `org-insert-link'.

Good. This explains it.

I think it's unfortunate that link escaping should have been changed in
a backward-incompatible way.  Seems like the "right" thing to do would
have been to add a fallback to the old interpretation if the new one
failed.

True, but the problem is that AFAIK there is now way to
programmatically check if the new escpaing/unescaping fails. There is
this function:

http://orgmode.org/worg/org-hacks.html#check-old-link-escapes

,----
| Starting with version 7.5 Org uses percent escaping more consistently
| and with a modified algorithm to determine which characters to escape
| and how.
|
| As a side effect this modified behaviour might break existing links if
| they contain a sequence of characters that look like a percent escape
| (e.g. [0-9A-Fa-f]{2}) but are in fact not a percent escape.
|
| The function below can be used to perform a preliminary check for such
| links in an Org mode file. It will run through all links in the file
| and issue a warning if it finds a percent escape sequence which is not
| in old Org's list of known percent escapes.
`----

that might at least tell you if there is a problematic link in an Org
mode buffer. What to do if the func finds a possibly problematic
sequence depends on the link. In the "%dave"-case escaping the percent
sign (% => %25) could be sufficient.
