Re: [libreoffice-users] compose characters

[Udvarias Ur]

Dear Thomas,

OOPS! My bad. I could not find the character you want in the 
"freedesktop.org" list.


However, I did find 2 versions of the character (one with a short bar 
the other with a long bar) in the "Character Map" program. You'll find 
them in the "STIXSizeOneSym" font.

All I ever get is a diacritical mark either left or right from the M.
I would appreciate if someone could point me in the right direction.

While googling about this, I also found some talk a "autocorrect

Yet, I cannot make this work either.
I suppose, there is a trick for this one too.

Dear Thomas,

The easiest way to do this is to use the "System Settings" program.

This will enable you to use the compose character key with literally 
everything on your system.


For instructions go to

keyboard layout - How can I enable Compose key? - Ask Ubuntu

https://askubuntu.com/questions/70784/how-can-i-enable-compose-key

Once you've set it up, you can see all the characters that are available 
to you at


https://cgit.freedesktop.org/xorg/lib/libX11/plain/nls/en_US.UTF-8/Compose.pre

It is not you, each font sets metrics for positioning the combining
diacritics--many get it wrong.

For example type "u+004du+0305", leaving the cursor after the 5. Then enter 
an +x to toggle--that will combine the glyphs, but position of the
overbar will vary by font.

Liberation Serif is just wrong. Dejavu Serif and Dejavu Sans are correct, as
is Linux Libertine G--but coverage is spotty.
 
Noto Sans and Noto Serif are about the most consistent.

For above marks -- U+0305, or U+035e
For below marks -- U+0332, or U+035f

Thomas, perform a search for «Adding Buttons to Toolbars» in LO Help and
follow the instructions. The button you want to add - and use when typing
in your « M» - looks like a lower-case «a» with a bar over it (ā)

Hope this helps !

Henri

Aren't vectors normally indicated by a bar *under* the letter?

I know there is something like "composing characters", but I cannot 
get it right. All I ever get is a diacritical mark either left or 
right from the M. I would appreciate if someone could point me in

You need a "combining" character. Suggestions are Unicode U+0304 
"Combining Macron" or U+0305 "Combining Overline". Enter your letter 
(M) and, with the cursor immediately after it, enter the combining 
character - probably using Insert | Special Character... . You will 
need to use a font that includes the combining character and handles 
it properly: not all fonts do.


While googling about this, I also found some talk a "autocorrect 
options" using : : Yet, I cannot make this work either. I suppose, 
there is a trick for this one too.


I don't think AutoCorrect helps you create such characters, but it 
may be useful if you need the combined character often. Instead of 
inserting the special character each time you need it, you could set 
up a replacement so that typing a code - perhaps "M#" or "M:" or even 
"M-" - would autocorrect to what you need. An alternative is simply 
to type such a code and then perform a global Find & Replace after 
you have prepared your text, of course.


I trust this helps.

[libreoffice-users] compose characters

[Thomas Blasejewicz]

Good afternoon
I have to enter into a technical text a capital "M" with a short bar on 
top of it.

Some sort of mathematical expression indicating a vector.

I know there is something like "composing characters", but I cannot get 
it right.

All I ever get is a diacritical mark either left or right from the M.
I would appreciate if someone could point me in the right direction.

While googling about this, I also found some talk a "autocorrect
