Can someone please explain how fonts in MOS work? It is confusing me.
In system preferences I can choose fonts from the directory
System:MorphOS/Fonts. These are system fonts. So I see no way to add the
fonts from my personal drawer like sys:fonts to the list in a font
requester. Also, although Ambient can use TTF fonts the directories in
System:MorphOS/Fonts like _ttf and so on do not seem to be considered for
font selection because those fonts do not appear in the font requester for
"other texts".

Then there is Scribble which has a checkmark in the settings for "use
TTEnigine" which is the system standard for TTF as far as I understood. So
why is there a checkmark to enable it? And what does it really do? When I
click on the font selection before and after the checkmark is set the font
list is the same in both attempts. What should be the difference? Where is
the font for "Output" used instead of "Editor"? And how can I tell it to
use fonts from another directory? The problem is that I can copy text from
another language to Scribble window but then I only see rectangles because
I can not change the font to one that has these characters.

Then there is OWB. It uses the fontconfig mechanism. How does this work and
for which programs? It is said that I can add an own directory to the font
directory list in fonts.conf file. But this contains many directories
which are all not used in Ambient, MUI, Scribble, OWB ...

<!-- Font directory list -->

<dir>SYS:Fonts/_pcf</dir>
<dir>SYS:Fonts/_pfb</dir>
<dir>SYS:Fonts/_ttf</dir>
<dir>MOSSYS:Fonts/_pcf</dir>
<dir>MOSSYS:Fonts/_pfb</dir>
<dir>MOSSYS:Fonts/_ttf</dir>
<dir>SYS:Fonts</dir>

There are many fonts inside these directories which do not show up in font
requesters.

Altogether there are 3 fontconfigs:
System:MorphOS/Fonts/Fontconfig
System:Fonts
System:Applications/OWB/Conf/font

So although there are system settings and user settings there still have
to be program individual settings?

Then in OWB in the preferences fonts I *really* can set a font from my
list of sys:fonts. But size and font type are set separately, not like in MUI
and other settings together. Why is it separated?
And on next update of OWB the settings of fontconfig become overwritten so
I always have to configure it again to use my fonts in sys:fonts.

And then there is another font drawer with fonts.conf in the OWB drawer.
This seems to be no more in use but it uses another setting. Why this and
not the system setting or the MUI setting?

Then there is the font requester itself. It has names for font collections
and I can add a new one. But then nothing happens, so how and why should I
add something there? It can be found in sys:fonts_collections but what to
do
with them? In the font requester I can add a collection but not assign
fonts to it or do something else so what is the use of defining a
collection there?
Then the collection also has a number column. This must be "#" instead
because it is the amount and not an ordering number.
Then there are styles for the fonts. One of them is "Normal". What is
normal other than nothing special is selected? And why are these styles
only possible in MUI font settings but not in Ambient or Scribble
settings?

Also, there is System:Tools/FTManager. It says it installs fonts. Why is
it needed to "instalL" a font and not just copy it to the fonts: directory?
does it more than copy the file there? Because the destination path fonts:
is already in the fonts.conf file. Also, as far as I see it lists all
files
from System:MorphOS/Fonts. So it offers to install them to Sys:Fonts, is
that right? What is the use of this operation because they are already in
the system drawer.

FTManager cna show previews of the fonts but only a very small one with a
few characters. Can this be set bigger to display more or all characters
of a font? And can it read fonts from other directories, too? Currently it
onyl shows the system directory.

And there is the Keystroke utility which shows some shortcuts to enter some
characters but only for one fixed font (which one?) and only for the first
few characters. Can it show the same for all characters in a font? How can
I do that?

So all this font topic in MOS is very much confusing because there are so
many different ways for settings and most of them are not documented. Can
someone please clarify this?
