Lars,
Thanks for the explanation. The display opacode will indeed produce
these Unicode characters for these dot patterns. These are 16- or 32-bit
characters, depending on how liblouis and liblouisxml were compiled. If
you use liblouis directly in your applications, you will get the Unicode
characters. However, to get them from liblouisxml or xml2brl you need to
specify the output encoding. The default encoding is to 8-bit
characters. To get 16-bit characters specify
outputEncoding utf16
in your configuration file. For 32-bit characters use utf32
You are "pushing the envelope". I'm glad you are trying these things.
John
