Diacritical marks on Greek letters

[d_abbatelli]

Hello

I need to type (not in "formula style", but as plain text) a greek letter with a diacritical mark on top of it.

I'm able to type latin letters with the diacritical marks: I just type the letter, then I open the special characters and I add the diacritical marks.

When I use greek letters instead of latin letters, the same process doesn't work. I insert the greek letter (either inserting it from the "special characters" panel or directly switching my keyboard to greek and typing it) and then I add the mark, but it ends up after the letter and not on top of it.

Whit the "formula editor" I would just write:

Code: Select all

dot %omega 

to attain what I want, but then I can't change the font, the color and so on.

What can I do?

Omega with a dot over it is not, I believe, used in either Modern or Ancient Greek and omega followed by Unicode U+0307 produces a dot to the right of the omega as you say.

In Math you should be able to change the font of the omega if you open the Symbols dialogue (from the icon in the toolbar or Tools>Catalog...), select the omega in Greek (or iGreek) and then click edit.

See here for changing the colour:

U+03C9 GREEK SMALL LETTER OMEGA, followed by U+0307 COMBINING DOT ABOVE seems to work for me. The dot is not precisely centered over the character, but not far off.

I think it's another of those font things – better in some fonts than others.

I have no problem typing in Greek letters including ones with dialytika and tonos (such as άύϋίϊόέήώ) using the Greek layout on Windows 7/OpenOffice.org 3.3.0/LibreOffice 3.4.4. So, please, provide more details on your problem.

I think this may be something in mathematics. There is a dot notation "often used for time derivatives such as velocity and acceleration".

ω is often used for angular velocity

so ω with a dot over it would be angular acceleration (though that may also be represented as α).
