ipad上的OneNote在查看Visio文件显示乱码

Question

我在电脑上使用Visio做了一个思维导图，随后在OneNote中添加了该文件。本来一切都很正常，直到刚才我编辑了这个思维导图，再用我的ipad打开Onedrive时，就显示乱码了。我尝试过再次同步、APP重启、设备重启，还是没用。并且奇怪的是，只有这个笔记本内所有的Visio图像显示乱码，另一个笔记本就是正常的。而且，我思维导图的字体是宋体和仿宋，应该不存在是字体没有的问题。

Hi,

This appears to be a limitation of OneNote on iPad, not a problem with your Visio file or fonts. OneNote for iPad does not fully support rendering embedded or linked Visio (.vsdx) content, especially when the file is edited on a PC and then viewed on iOS. When this happens, text inside the Visio object can appear as garbled characters even though it looks correct on Windows.

This occurs because OneNote on iPad relies on a simplified rendering engine and does not process Visio diagrams the same way the Windows version does. Font choice (including Song or imitation Song) is not the main issue here—the Visio object itself is not fully supported on iOS.

To work around this, first export the Visio diagram as an image (PNG or JPEG) and insert that image into OneNote instead of the Visio file. Second, if you need to keep the Visio file editable, store it as an attachment and view or edit it only on a PC. Lastly, you can also open the notebook in OneNote for Windows or OneNote on the web, where Visio rendering is supported.
