saya tidak pernah bisa mendapatkan terminal saya untuk menampilkan simbol unicode. misalnya, sebelum saya memiliki os saya sekarang, saya memetakan ctrl + a ke yunani Anda di vim, dan itu bekerja di komputer lain, tetapi tidak pada xterm saya saat ini. di sini adalah bagian yang relevan dari saya .vimrc:
set encoding=utf-8
"map control-a to mu
imap <C-a> <C-k>m*
juga, saya perlu menampilkan persamaan sympy di python, dan ini bekerja di komputer lain, tetapi tidak pada xterm saya saat ini. alih-alih ini:
$ 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 ⎠
saya mendapatkan ini:
>>> (sympy.sqrt(x**3/(x+1)), 1)
n ------- n
n n 3 n
n n x n
n n ───── , 1n
nnnn x + 1 n
Infact tampaknya hanya menggunakan nkarakter setiap kali itu tidak dapat menampilkan karakter unicode.
Aku berlari xterm dari ~/.xinitrcberkas dan pengaturan beberapa font dan warna untuk terminal di ~/.Xresources. di sini adalah semua informasi yang relevan yang dapat saya pikirkan:

saya juga berlari $ fc-listtetapi hasilnya terlalu besar untuk disisipkan ke pertanyaan ini. jadi saya taruh di sini
apa yang ditampilkan di browser saya:
/usr/share/fonts/truetype/freefont/FreeSansBold.ttf: FreeSans:style=Bold,получерен,negreta,tučné,fed,Fett,Έντονα,Negrita,Lihavoitu,Gras,Félkövér,Grassetto,Vet,Halvfet,Pogrubiony,Negrito,gros,Полужирный,Fet,Kalın,huruf tebal,жирний,Krepko,treknraksts,pusjuodis,đậm,Lodia,धृष्ट
apa yang saya lihat di terminal saya:
/usr/share/fonts/truetype/freefont/FreeSansBold.ttf: FreeSans:style=Bold,nnnnnnnnn,negreta,tunné,fed,Fett,nnnnnn,Negrita,Lihavoitu,Gras,Félkövér,Grassetto,Vet,Halvfet,Pogrubiony,Negrito,gros,nnnnnnnnnn,Fet,Kalın,huruf tebal,nnnnnn,Krepko,treknraksts,pusjuodis,nậm,Lodia,nnn
Menariknya, beberapa karakter "spesial" muncul di terminal saya, tetapi sebagian besar dilacak oleh n. Anda dapat melihat dalam output sebelumnya bahwa tidak ada yang получеренdapat ditampilkan, tetapi karakter akhir tučnédapat ditampilkan (sementara tengah čtidak dapat - itu diganti oleh n)
sesuai komentar @ apaul tampaknya xterm tidak memuat font yang tepat. cobalah untuk mengatur kelas dummy sehingga tidak memuat sumber daya xterm:
$ 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 :)
semua yang tersisa adalah mencari tahu mengapa xterm tidak dapat mengatur font menggunakan ~/.Xresoureces, dan untuk membuatnya bekerja. sepertinya ada sesuatu yang harus mengesampingkan pengaturan font?
sebenarnya saya hanya berpikir untuk mencoba perintah di atas dengan font terminus, dan sepertinya inilah masalahnya:
$ xterm -class Foo -name foo -u8 -fa "Terminus"
$ # the following commands are all executed in the resulting terminal:
$ echo -e "\xE2\x98\xA0"
n
mungkin terminus tidak terpasang dengan benar? atau sedang dipetakan ke sesuatu yang lain. bagaimana saya bisa mengetahuinya?
-fa "DejaVu Sans Mono:size=11:antialias=true"Namun, saya tidak mengerti Anda -jsdan -fullscreenopsi. Versi xterm saya tidak memahaminya. xterm -versionOutput saya X.Org 6.8.99.903(253).
lsof -p $PPID | grep fontsdan memeriksa daftar font yang dapat dilihat oleh xterm fc-list.
xterm -class Foo -name foo -u8 -fa "DejaVu Sans Mono:style=Book"? (di sini kita menetapkan kelas dummy dan nama sehingga tidak memuat XTerm*sumber daya.)
