@SBA:
Please have a look.
I found "a" reference:
http://www.lingvozone.com/languages/Language%20Information9.htm

An in IZ the issue 13981 mentions it shortly.

Tools - AutoCorrect - Options
Tab "Exceptions"
Choose Language "Dutch (Netherlands)"
-> See that the exception list "Words with TWo INitial CApitals" for NL only has
the entry "OOo"

Your short-term solution:
Add the Words you need to this list

The Sledgehammer solution:
On Tab "Options", uncheck "Words with TWo INitial CApitals" twice, OK

The real Solution: 
Provide af full list of all words and attach it to this issue. Then it can be
added to the office by default.
Note: On tab "Exceptions", when you select language English (USA), you can se a
nice list of MHz, GHz, CDs and PCs that are likely to be useful when used for
Dutch, too.

Change issue type to "Enhancement", adjusting summary

This is not the desired solution. As I mentioned, the vowel "IJ" in Dutch ALWAYS
is written with two capitals. So I would have to add IJs, IJzer, IJzel, IJl,
IJdel, IJzig, IJnemuiden, ...

What amount of words are we talking about? 100, 1000, 10000?

Note that it is not neccesairily YOU to provide such a list. I just thought you
might have one at hands since you digged into this already.

The "List" solution would work without any "real code" change, it is just adding
local data. In my opinion is realistic to get this done for OOo 3.2.

Yes, one might think of the AutoCorrection ignoring "IJ" for Dutch as you propose.
Or being able to add "wild cards" like "IJ*" into that list. All this sounds
"expencive" in terms of performance (each word being checked "Do you start with
IJ?") and developer ressources to do it. I truly believe that such a Feature
wisch (NEW code implemented and tested, maybe even some UI change to control
this, then with a full-blown specification and new Test Cases being written and
documentation being translated) would get very very old because there is "bigger
fish to catch" in the forseeable future. Fixing REAL defects has a higher
priority than this Feature that would serve "only" (sorry... :-) the users of
Dutch. Means: Bring on a developer to do so or wait a long long time without any
change in the Office.

Thus I still favor the "List solution" as I see no other realistic one.
Put OS and TL on c/c.

Note: This issue should probably be split up into two, since one part is the
spell checker and the other is auto correction, and both have nothing in common.

I would regard adding "wild cards" to the autocorrection exceptions list as the 
worst possible solution. For me, as a simple outsider from the OpenOffice code, 
I don't know about costs for changing that code to work for this issue. The 
structural solution would be regarding "ij" as a single "letter". The quick 
solution is indeed to add every word starting with "IJ" to the autocorrection 
exceptions list, as there won't be too much.

I believe this is some l10n issue!

Changed component to l10n. Reassigned to VA.

This issue is about adding a list (see summary).
-> The enhancement issue "treat letter combinations differently" must be written
seperately.

Adding myself, digro and simonbr to the cc

@Simon please comment on this.

A list of 338 words starting with "IJ" from the OpenTaal word list can be
downloaded from here: 
http://simonbr.xs4all.nl/wiki/index.php/IJ-woorden

Note that there may exist other Dutch words that start with IJ, for example
compounds formed from one of these. So adding these words to the exception list
will not completely fix the problem.

Just curious: Why are in Dutch no double letters (ligature) used? It seems that the 
most important fonts contain these characters: IJ or ij

But maybe I am wrong. ;-)

I don't think an exception list is a very elegant solution for this. The letter
IJ is a feature of the Dutch language and it would be best if the spelling
engine or whatever part of the programme controls initial caps correction would
recognize this. I don't think this that in MS Word this is solved by an
exception list.

Also, how do you add items to the exception list? The provisional list referred
to here already contains 338 items. Are you supposed to add these one by one
through the software's dialogue? A hell of a job that doesn't really deserve the
label 'user friendly'.

This is not the only Dutch language issue in Open Office, by the way.

To explain: Simon's list is admirable, but it can never be complete. To take
just a few examples: it has the word IJsland and IJslands, but then there's also
the word form IJslandse. Similarly for IJzig -- it does have IJzige, but then
ijzigst and ijziger and ijzigste are all of them also *possible* word forms. 

Trying to simply compile a list of "all" possible words is a never ending story.
The software just has to recognize that, weird as it is, IJ is a single letter
in Dutch and should be treated as such.

Come on, guys! If Microsoft can, so can you. 

So we did :-)
By updating the Dutch (NL) dictinary extension for OOo 3.3 (see issue 114603),
the "Capital IJ" issue is fixed. "Ijsselmeer" gets corrcted to "IJsselmeer",
same for "Ijsland", "Ijslandse"...

Looks like this issue can be closed as it was fixed at the best place, the spell
check extension itself. :-)

Reassigning issue to me.

Set to "WORKSFORME"

Hmmm... Just re-thinking this one.
The new spell checker dictionary alone does not solve the problem. While
writing, "IJ..." still gets auto-corrected to Ij... (and then marked as misspelled).
Thus any (incomplete) list will soothe the problem.
Reopening issue.

Reassigned to VA again.

Can someone provide me with an updated acor_nl-NL.dat, so I can check it in? TIA!

Reset assigne to the default "issues@openoffice.apache.org".
