Package: brltty
Version: 5.4-7
Severity: grave

I did get a new braille display awhile ago. I have been testing it and I have
noticed that braille table for the Finnish  language is broken. Reading text
works but It is impossible to write text in Finnish using the integrated
braille keyboard in the braille display. Writing text in Finnish language is
not possible because writing scandinavian letters (which are wery commonly used
in Finnish language) does not work. The following scandinavian letters are used
in Finnish language. Small letters: ä, ö, å. Capital letters: Ä, Ö, Å.

It seems that the braille table for the Finnish language has many lines which
define some weird control characters. Those lines conflict with lines defining
scandinavian letters . If I remove those conflicting control character lines
then both reading and writing text in Finnish works correctly.

I am a blind user from Finland so it is wery important for me that writing text
in Finnish works. My native language is Finnish so I am really using braille in
Finnish.

The braille table for the Finnish language is in the file:
/etc/brltty/Text/fi.ttb

First of all these lines define scandinavian letters used in the Finnish
language. These lines are correct and SHOULD NOT be changed:

char \xC4       (  345 7 )  # C4 ⡜ Ä [LATIN CAPITAL LETTER A WITH DIAERESIS]
char \xC5       (1    67 )  # C5 ⡡ Å [LATIN CAPITAL LETTER A WITH RING ABOVE]
char \xD6       ( 2 4 67 )  # D6 ⡪ Ö [LATIN CAPITAL LETTER O WITH DIAERESIS]
char \xE4       (  345   )  # E4 ⠜ ä [LATIN SMALL LETTER A WITH DIAERESIS]
char \xE5       (1    6  )  # E5 ⠡ å [LATIN SMALL LETTER A WITH RING ABOVE]
char \xF6       ( 2 4 6  )  # F6 ⠪ ö [LATIN SMALL LETTER O WITH DIAERESIS]


The problem described in this bug report is caused by the following lines.

This line is defined incorrectly and conflicts with the small letter "ä" ("ä"
in Finnish braille is dots: 3, 4, 5) :

char \x84       (  345   )  # 84 ⠜   [<control-0084>]


- This line conflicts with the small letter "Å" ("å" in Finnish braille is
dots: 1, 6) :

char \x86       (1    6  )  # 86 ⠡   [START OF SELECTED AREA]


- This line conflicts with the capital letter "Ä" ("Ä" in Finnish braille is
dots: 3, 4, 5, 7) :

char \x8E       (  345 7 )  # 8E ⡜   [SINGLE SHIFT TWO]


- This line conflicts with the capital letter "Å" ("Å" in Finnish braille is
dots: 1,6,7) :

char \x8F       (1    67 )  # 8F ⡡   [SINGLE SHIFT THREE]


- This line conflicts with the small letter "ö" ("ö" in Finnish braille is
dots: 2, 4, 6) :

char \x94       ( 2 4 6  )  # 94 ⠪   [CANCEL CHARACTER]


- This line conflicts with the capital letter "Ö" ("Ö" in Finnish braille is
dots: 2, 4, 6, 7) :

char \x99       ( 2 4 67 )  # 99 ⡪   [<control-0099>]


I really do not know for what and how those control characters are used, all I
know is that if those control character lines are not commented out then
writing text in the Finnish language is not possible. Those control character
lines should be commented out, removed or changed so that those do not conflict
with any other line.

I have compared the Finnish braille table with Swedish braille table because
Swedish is the second official language in finland. It seems that the Swedish
braille table does not define those control characters.

The braille table for the Swedish language is in the file:
/etc/brltty/Text/sv-1996.ttb

How to reproduce this bug:

1) select the Finnish language in the file:
/etc/brltty.conf

Uncomment this line:

text-table      fi      # Finnish

2) Restart brltty
3) connect Braille display which has integrated Braille keyboard
4) start e.g text editor
5) Try to write these scandinavian letters using the integrated Braille
keyboard in the Braille display:

- small letter ä )braille dots: 3, 4, 5)
- small letter ö (braille dots: 2, 4, 6)
- small letter å (braille dots: 1, 6)
- capital letter Ä (braille dots: 3, 4, 5, 7)
- capital letter Ö (braille dots: 2, 4, 6, 7)
- capital letter Å (braille dots: 1, 6, 7)
