Kivy 没有正确显示(孟加拉语)加入角色?

然后依次发出以下三个命令:

Then issue the following three commands sequentially:

sudo pip3 install cython
export USE_PANGOFT2=1
export KIVY_TEXT=pango

Cython 安装可能会收到 Requirement already compatible 消息，没关系.

You may receive Requirement already satisfied message for Cython installation, which is ok.

现在使用以下命令卸载 Kivy:

Now uninstall Kivy with following command:

sudo python3 -m pip uninstall kivy

并使用以下命令安装 Kivy:

And install Kivy with following command:

sudo pip3 install kivy

成功重新安装 Kivy 后，您可以运行以下示例:

Once Kivy is re-installed successfully, you can run the following example:

import os
os.environ['KIVY_TEXT'] = 'pango'
from kivy.app import App
from kivy.lang import Builder


APP_KV = """
BoxLayout:
    Label:
        text: "সকালে"
        font_size: '48sp'
        font_name: 'font/kalpurush.ttf'
"""

class MainApp(App):
    def build(self):
        return Builder.load_string(APP_KV)

if __name__ == '__main__':
    MainApp().run()

KIVY_TEXT 环境设置可能不需要，因为之前已经导出.但这是为了展示如何选择文本渲染器.您需要在名为 font 的子目录下拥有字体文件 kalpurush.ttf(或任何其他孟加拉 unicode 字体文件).

The KIVY_TEXT environment setting may not be needed as already exported earlier. But this is to show how you can select the text renderer. You need to have the font file kalpurush.ttf (or any other bangla unicode font file) under sub directory named font.

运行程序时的Kivy日志如下:

The Kivy log when you run the program is as follows:

请注意，文本提供程序是 pango.

Please note that the Text provider is pango.

程序的输出:

因此，文本正确呈现.您可以使用任何其他复合孟加拉字母进行测试，它会正确呈现.

So, the text is rendered correctly. You can test with any other compound bangla letters, it will render correctly.

对于 Windows 等其他平台，挑战在于正确安装 pango.这样做可能并不简单，因为到目前为止我还没有找到简单的方法.可能是 pango 需要从源代码编译它的依赖项.

For other platforms like Windows, the challenge is to correctly install pango. It may not be trivial to do so as there is no simple way I have found so far. May be pango needs to be compiled from source with it's dependencies.
