xtermはUnicodeを表示しません

私の端末にUnicode記号を表示することはできません。たとえば、現在のOSを使用する前は、vimでCtrl + Aをギリシャ語のmuにマップしていましたが、他のコンピュータでは動作していましたが、現在xtermでは動作していません。私に関連する部分は次のとおりです.vimrc。

set encoding=utf-8
"map control-a to mu
imap <C-a> <C-k>m*

また、他のコンピュータでは動作しますが、現在xtermでは動作しないPythonでSympy方程式を出力する必要があります。代わりに：

$ python
Python 2.7.3 (default, Mar 14 2014, 11:57:14) 
[GCC 4.7.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sympy
>>> x = sympy.symbols('x')
>>> sympy.init_printing()
>>> (sympy.sqrt(x**3/(x+1)), 1)
⎛     _______   ⎞
⎜    ╱    3     ⎟
⎜   ╱    x      ⎟
⎜  ╱   ───── , 1⎟
⎝╲╱    x + 1    ⎠

わかりました：

>>> (sympy.sqrt(x**3/(x+1)), 1)
n      -------   n
n     n    3     n
n    n    x      n
n   n   ───── , 1n
nnnn    x + 1    n

n実際には表示できないたびにUnicode文字を使用しているようです。

私は~/.xinitrcファイルからxtermを実行しています~/.Xresources。これは私が考えることができるすべての関連情報です。

@apaulのコメントによると、xtermが正しいフォントをロードしていないようです。 xtermリソースをロードしないようにダミークラスを設定してみてください。

$ xterm -class Foo -name foo -u8 -fa "DejaVu Sans Mono:style=Book"
$ # the following commands are all executed in the resulting terminal:
$ echo -e "\xE2\x98\xA0"
☠
$ # the above skull actually shows up now. and so does the unicode
$ # output from sympy and also vi can display greek symbols now :)

残っているのは、なぜxtermを使ってフォントを設定できないのかを調べ~/.Xresourecesて動作させることです。何かフォント設定を無視する必要があると思いますか？

私は実際にターミナルフォントを使って上記のコマンドを試しましたが、それは問題のようです。

$ xterm -class Foo -name foo -u8 -fa "Terminus"
$ # the following commands are all executed in the resulting terminal:
$ echo -e "\xE2\x98\xA0"
n

端末が正しくインストールされていませんか？または他のものにマッピングすることもできます。これをどのように発見できますか？
