I can’t tell which unicode range those specific code points belong to,
but
if you’re sure the hex data represents utf-8, and I understand what you
are
asking for correctly, try something like:

line.scan(/(…)/).each do |code_point|
puts code_point.pack(‘H*’)
end

Depending on where the data is coming from, you might need to flip the
bytes
to account for endianness. I don’t believe that will be an issue on
linux.

Hope it helps,

What do you meant “convert to utf-8”?

Those hex characters are very unlikely to be UTF-8. See
http://en.wikipedia.org/wiki/UTF-8

AA = second, third or fourth byte of multi-byte sequence
3F = single-byte character (?)
32 = single-byte character (2)
01 = single-byte character (ctrl-A)
86 = second, third or fourth byte of multi-byte sequence
1F = single-byte character (ctrl-?)
… etc

Apart from D6 there are no “start of n-byte sequence” characters

Try typing “file /home/pt/myday”, which will attempt to identify what
sort of file you actually have.

‘file’ knows many file formats - look at /usr/share/file/magic or
/etc/magic depending on your system. But this isn’t one of them. Neither
is the data UTF-8 text, or at least, the header isn’t.

You could look to see if there are any snippets of readable text in it:

strings /home/pt/myday | less

But if not, then it really is just binary data, and its meaning will
depend on what program wrote it in the first place.
