python - Matplotlib 不显示不同语言的字符（印地语）和其他字符，如表情符号
问题描述
该函数只是获取一些视频的数据并尝试在水平堆叠条形图中表示它们。参数 data 是一个列表字典{'key' : [ ], 'key2' : [ ].....}。示例数据（图像中结果的数据）如下所示。出现的问题是它无法表示其中包含印地语字符和表情符号的数据（参见 y 轴）。问题可能是由于字体的 Unicode 集。我尝试更改 yticks 的字体，但没有任何效果。

解决方案
按如下方式渲染印地语字符：首先运行 Linux 命令fc-list :lang=hi family（参见https://linux.die.net/man/1/fc-list）生成完整的印地语字体列表，然后从那里选择Arial Unicode MS.
将此添加到 matplotlib 字体参数，以及其他 2 个：
mpl.rcParams['font.sans-serif'] = ['Source Han Sans TW',
'sans-serif',
'Arial Unicode MS' # fc-list :lang=hi family
]
emojis接下来，使用可以安装的软件包将表情符号转换为文本pypi（使用命令：） pip install emojis：
import emojis
labels = list(data.keys())
labels_decoded = [emojis.decode(label) for label in labels]
这会生成表情符号的文本描述，而不是它们的图形表示（例如:airplane:）。对于图形表示，您可以尝试使用https://github.com/matplotlib/mplcairo
