If I create a text cell and type some greek text, most of the symbols are italics as if the cell had an Input style. It doesn't happen with latin characters. I recollect that it is impossible to fix it, but I can't find the source where I read it.

Perhaps someone knows a workaround ? The following screenshot is from Mathematica 8/Linux.

EDIT1: I just noticed that writing capital greek letters works fine (the letters are normal, not italics). The following screenshot is from Mathematica 9.0.1/OSX Mavericks.

Does that piece of information ring any bells to anyone on what might be the underlying problem ?

EDIT2: I also found this link describing a workaround by using custom modified unicode mapping files. I can't check it right now as I'm not near my Linux installation.

EDIT3: I did try it though in Mathematica 9.0.1/OSX (although the article talks about Mathematica 7&8/Linux), and it works great! Here is the relevant screenshot:

EDIT4: As pointed out by @ybeltukov in comments, the workaround is to set the third column of to 0 (zero) for Greek letters so that the default font is picked for them.

EDIT5: This workaround doesn't anymore apply to Mathematica 10. I cannot find the file. There's another effective workaround though, described here in Alexey's answer.

Explanation of your last link: just set the third column of to 0 for greek letters to choose the default font for them. – ybeltukov Nov 1 '13 at 21:13
People, is it ethical to answer my own question that I put a bounty on ? – Zet Nov 1 '13 at 21:13

Font for the Greek letters is defined in

0x03B1      N       -2      0x61        # \[Alpha]
0x03B2      N       -2      0x62        # \[Beta]
0x03B3      N       -2      0x67        # \[Gamma]
0x03B4      N       -2      0x64        # \[Delta]
0x03F5      N       2       0x65        # \[Epsilon]
0x03B5      N       -4      0xb6        # \[CurlyEpsilon]
0x03B6      N       -2      0x7a        # \[Zeta]

The third column defines the font. You can set it in corresponding lines to 0 (default font).

This approach was used in your link. Difference between the original file and the file in this link:

This is generally true, but not for Mathematica 10. In latter case one should follow DBM's answer below or, more generally,…. – Alexey Bobrick Sep 30 '14 at 19:24
@AlexeyBobrick This answer was written before Mathematica 10 release :) – ybeltukov Sep 30 '14 at 19:42
Yes, which makes it funny in a way. Quite a few times I found good solutions to problems, which don't work in V10 anymore. – Alexey Bobrick Sep 30 '14 at 19:45

For OS X Mathematica v10, one can edit /Applications/ to enable writing Greek letters in any font supporting them. In my case, I wanted µ (\[Micro]) to display with my preferred font (CMU Bright Roman) rather than the Mathematica font. The solution was to open, copy the string within CompressedData[str], paste it into fontMap=Uncompress[str] in a new workbook, delete 181 (character code for \[Micro]) at position 32 of fontMap[[1,2]] by running fontMap[[1,2]]=Drop[fontMap[[1,2]],{32,32}], recompress by running Compress[fontMap], copy the resulting compressed string, past it over the original string within CompressedData[str] of and then save I kept a backup of the original file. Now Style["µ", FontFamily -> "CMU Bright"] displays µ with my chosen font.

I suppose this could be done for other Greek letters as well.

Thanks @DBM! So, I should delete all character codes for Greek letters in the font map and then use Style[] to choose a Greek font ? – Zet Aug 25 '14 at 21:19
I think that should work, but have not tried this on more than one greek letter. Keep a backup of the original file... – DBM Aug 26 '14 at 5:13
You might like to check…, where I elaborate a bit on your answer. – Alexey Bobrick Sep 30 '14 at 19:22
@Zet: Yes, you can make Mathematica to keep all the greek characters by just one command, see the link above this comment. – Alexey Bobrick Sep 30 '14 at 19:23
For the record: @AlexeyBobrick's solutions worked perfectly! – Zet Nov 2 '14 at 3:07
