That was a difficult birth. But it works now. Thanks you so much for
your patience. Now It will be very easy to program some function keys on
the Logitech keyboard to shortcut the use of the mouse.

Re: [oXygen-user] How to type an UTF8 symbol in text as well as in author mode

2018-02-19 Thread Eliot Kimber

The (hex.) column is the UTF-8 encoding of the character, that is, the sequence 
of bytes.

 

The actual Unicode character number is the value in the first column, e.g., 
\u2190.

 

So you should be able to type 2190 and get the character you want.

 

Unicode is the character set and the character numbers (code points) are 
independent of how the characters are encoded.

 

The encoding is how the characters are translated to bytes when written as a 
byte sequence.

 

The Unicode standard defines a number of encodings, including UTF-8 and UTF-16.

 

So there are not “UTF-8 characters”, only UTF-8 encodings of Unicode characters.

 

The UTF-8 encoding was designed so that it is identical to ASCII for the first 
127 or 255 characters (depending on which version of ASCII you’re looking at). 
But after character 255 it takes at least 3 bytes to encode a character.

 

Cheers,

 

E.

Hi Bernhard,

The action converts the Unicode codepoint, that is 2190 and not its 
UTF-8 encoding, so just type 2190 and invoke the action.

Oh, how quickly we forget certain things. :)

oXygen has had the ability to enter UTF-8 characters in the first
plane by their four character hexadecimal code point value since
version 17.1. I can't recall what the default hotkey is for invoking
it because I changed mine (back) to F8 as soon as I installed that
version. I believe I've still got the plugin you guys provided me
during my trial period for 17.0.

Anyway, if Bernhard is happy with using hex instead of int, that's the
solution instead of the Windows alt sequences (or the Mac alt/option
sequences either, for that matter).

Accessing characters in multiplanes beyond the first is difficult in
most programs, including oXygenXML. Obviously XML can handle it, but
the accessing problems are twofold:

1. Entering a hexadecimal character comprised of five or six hex
characters on the remaining 16 planes (i.e. 0x1 to 0x1f).

2. Rendering characters which can only be displayed using multiple
fonts and guaranteeing font fallback capablities.

I have only one program which can handle both of these natively for
editing and that's GNU Emacs, but in those cases where I need to delve
into the upper multiplanes I can open a file from oXygen in Emacs and
that'll do for now.

It might be worth having a look at extending the hex entry feature to
enable a way to enter a hex value of grater than 3 bytes (4
characters), but oXygfen takes that input differently to other
programs and so it might be tricker. Emacs, LibreOffice and other
programs work by activating the hex input function (it's "M-x
insert-char" in Emacs) and then entering the code point hex value. In
oXygen you enter the hex value as four characters in the document and
then press the hotkey which reads the preceding four characters and
transforms them.

As for font fallback, there's pretty much no options for handling that
in oXygen, but there are effective workarounds by doing sneaky things
with CSS in the source files as well as the output formats.

I've got my own little Unicode cheat sheet which has been gradually
growing over the last decade or so and covers most of this in more
detail. Bear in mind two things: first, it's a personal cheat sheet
that I only share because it often answers frequent questions I hear
elsewhere; and second, it's a "living document" that gets updated
frequently.

That said, it's here:

https://www.dropbox.com/s/8jifzcc8qks5cef/UnicodeNotes.pdf?dl=0

Or to download it:

https://www.dropbox.com/s/8jifzcc8qks5cef/UnicodeNotes.pdf?dl=1

It's only ever released as a PDF because of all the font/glyph
embedding. It claims or attempts to export as PDF/A-1, but only to
ensure that font embedding and it probably won't pass preflight
checks (nor does it need to).

For those few readers of this list who also use Emacs, the last three
pages of that file include those portions of my Emacs init file which
specify the fallback fonts using fontset default. I've got coverage
from 0x to 0x2 and where things occasionally misbehave,
they're easy to identify with the aid of the binding on F16 (i.e. M-x
describe-char).

Finally, my current favourite code point checking tool, for any system
with Perl installed, is unum.pl, available here:

https://www.fourmilab.ch/webtools/unum/

The current version of the cheat sheet discusses it on page 23, but
here's a nice example of what it does:

bash-4.4$ unum.pl 0x1f926
Octal Decimal HexHTMLCharacter Unicode
0374446 129318 0x1F926 "臘" FACE PALM
bash-4.4$

Obviously some of us can see that character properly and some can't,
but you all know which it is.
