Hello,
I cannot promise a success but please try following:
Do not enter the character but use the copy / paste function.
Please go to the first appearance of the escape sequenzce, highlight this
character with command B1B4B9 and then press c+B8B9 to copy it into the
clipboard.
Then open the find command use v+B8B9 to paste the character into the "find
what" edit box. And confirm the search.
I hope this will bring you to the real existing escape sequence positions.
Some further explanation: The unicode to braille table (u2b file) is
responsible which braille pattern is presented for the unicode value of a
code page or simple character or
The braille to unicode table (b2u file) is responsible to enter an assigned
unicode value when you enter a braille pattern
For logical reasons the b2u file only can have 255 unicode values each for
one 8 dot braille pattern.
The u2b file has much more entries and different unicode values can be shown
with the same braille pattern.
Mit freundlichen Grüßen - Best regards,

Betreff: [varioultra] How to search for escape characters in the word
processor please?
Hi all,
I recently upgraded my VarioUltra 20 with the 1.4 beta version.
The text file which is loaded into the word processor is a "typescript"
generated by the linux "script" command.
I'd like to extract the information I need from this file in order to write
an internal report.
The first thing I did is to remove from the file, all the information I am
100% sure not to need: progress reports of commands, other intermediate
useless state reports, bad commands and their results, ...
From what now remains in the file, I need to be sure there are none of those
"escape sequences" which are used by linux to pretty print the output on the
screen.
I thought I could "find" the escape character. I opened the "find" dialog box
by pressing ?+B8+B9. In the "find" edit box, I pressed B1+B2+B3+B5+B6+B7+B8.
This is how the escape character is encoded in the German Computer Braille
table I'm using for input and output. At least, it is the way it is shown on
the display each time I read one.
The "Match case" checkbox is unchecked. The "Whole words only" checkbox is
unchecked. The "Search backwards" checkbox is unchecked and I'm at the
beginning of the document. The "Replace" checkbox is unchecked. When I press
the "OK" button, I always receive a "Not found" hint message although while
reading by hand, I can still find escape characters.
Now if I place the cursor somewhere in the text, voluntarily type
B1+B2+B3+B5+B6+B7+B8, go back to the beginning of the document and enter the
"find" tool, the character I typed is found. But, when I hit "Find next", a
true escape character which was a few letters after the one I typed is not
found.
So, in the "EUROPA" braille tables, what is the difference between the real
"escape character" which is printed on the display as B1+B2+B3+B5+B6+B7+B8
and the same combination I type on the VU braille keyboard?
How should I use the "find" tool if I want to look for control characters
please?
Many thanks in advance. Have a nice day. ChD
