Try before you buy: Free demo version

This suite of tools adds full spell-checking capabilities to Acrobat.
You can now check and mark up regular text and bookmarks in addition to the standard check for form fields and comments which already exists in Acrobat.

Update IV (25-08-2016): New update for this tool! It can now handle ligatures symbols as well as end-of-line hyphenated words better than before.

Update III (18-06-2014): A new feature just added to this tool, allowing you to define "No Spell Check" zones, which the tool will ignore when it spell-checks the document.
Another improvement is the option to define whether or not to perform a case-sensitive spell-check. By default the check is case in-sensitive.

Update II: Now this script includes a batch process, which allows you to spell-check multiple files one after another (provided you have Acrobat Pro, of course).

Update I: A free demo version of this tool is now available here. It allows you to select a dictionary and then spell-check the first page of the currently active document.

The main menu of the suite looks like this:

The language dictionary selection looks like this:

Each of these dictionaries can be customized: Words can be added and removed from it, either using a simple input dialog or through a file (which allows adding or removing multiple words in one go).

When you run spell-check a document, the misspelled words are underlined and the suggestions for the correct spelling are added to the highlight:

Update: Added functionality to check just a part of the document. This is ideal if you have a single document consisting of multiple languages. You simply add "Spell Checking Zones" to your document, and only the words within those zones will be checked.

Here's how such a zone looks like (notice that only the misspelled words inside the zone were marked):

 

IMPORTANT NOTE:  This tool does NOT offer a way of fixing the found spelling mistakes, it just marks them on the page. To do so you would need to go back to the original file format and fix it there, or manually use the Edit Text command in Acrobat (not recommended, but possible).
