How should the content of the file read from the disk be converted to "Text"?

How should the content of the file read from the disk be converted to “Text”?

Either don’t convert, and just pass a string under the doc option, or split it into lines and pass it to Text.of.

Because I need to call changes.apply to generate the latest content and write it to the disk, and the apply function receives a ‘Text’, so I need to convert it on the server side. When intercepting, I should use the newline character ‘\n’ to Is it intercepted?
