Currently used Danish braille tables no longer exist

The table definitions in braille.py contain two Danish tables:

• da-dk-g1.utb (grade 1)
• da-dk-g2.ctb (grade 2)

Neither of these tables is available in the liblouis submodule at version 2.6.0. If the user selects these tables in a fresh copy of NVDA 2015.1, there is no braille output. The likely replacements are:

• da-dk-g16.utb (grade 1)
• da-dk-g26.ctb (grade 2)

But it might be desirable to also include the 8-dot variants. As I'm not Danish I can't evaluate the changes between the old tables and the new ones.

How are does tables in current 2.6.2? Since the upgrade to liblouis 2.7.0 (as proposed in #4777] comment 7) won't be there in time for 2015.2, I believe that this bug should be fixed regardless of the progress in #4777.

Hi,
Let me ask the LibLouis mailing list as to which tables should be used, and if so, I'll update the braille table module.
Cheers,
Joseph

They are also not available in 2.6.2. Depending on Joseph's results we could maybe switch to those new Danish tables, then update to 2.6.2 as per #4777 because these minor releases improve on the Danish tables as well.

Ug. This wasn't documented in the release notes for 2.6.0. Table renaming is a real problem for us, as it breaks existing users and new ones as well if it's not documented.

This shouldn't be blocked by #4777, as this needs to be done regardless and is actually more important.

Milestone changed from None to 2015.2

Worse, this was already in 2.5.4 and possibly older versions. I can't find any indication of this in NEWS, though. Maybe the build process should do a quick check on orphaned tables?

Joseph, thanks again for posting this to the liblouis list! Saved me quite some hastle since I'm not subscribed with my home address. I noticed you've got a response.
Here's a topic branch for this issue: https://bitbucket.org/dkager/nvda/branch/t4986

This patch doesn't enable da-dk-g18.utb for input as suggested in the e-mail because "very close to a clean 8 dots char to char table" isn't good enough. Currently there is no Danish input table either, and adding one that almost works will probably lead to tickets pointing out the places where it doesn't.

Should fix this ticket and possibly #2835 as well (MHameed?).
