Many unicode characters are missing from the standard braille table

[bramd]

Many characters such as bullets in lists on webpages and other Unicode characters such as letters with accents are not correctly displayed in braille.

It seems to display \x followed by a character code.

Needs to be fixed in liblouis. Also, there is no "standard" table; each table needs to be considered separately. Can you be more specific?

Replying to jteh:

This is tested with the US English 8 dot computer braille table, which is set as the default table in NVDA. I'll test with other tables and file relevant bugs with liblouis if needed. However it might be handy to show a "?" or some other indication if there is a character that's not in the used braille table. The current way of showing \x<charcode> is quite annoying to read. Not sure if this is NVDA or liblouis behavior though.

I'll update this ticket when I have more info.

It is liblouis behaviour. Furthermore, it breaks the mapping between input and output positions; see #499. A question mark or similar might be better, but note that this would be different for every table, so we might need some way to define a character to be inserted for "unknown" characters.

I tested this with the de-de-comp8.ctb table.

after sign \x00ff there aren't any signs any more. Unicode chars often begin with \x2 which aren't included here.

For example NVDA shows \0x20.. if you are in a table in Microsoft word. or for some quotes.
