fix(fs): support any UTF-8 path in writeFile

[SRutile]

improper input parsing

In the writeFile function, when path is a string that contains Chinese characters or spaces, and options.baseDir is not provided, it can lead to errors. This PR introduces a fix: when path is a string and contains Chinese characters or spaces, it converts such paths to URL format, thus preventing these errors. As a result, paths obtained from save dialogs can be directly used in the writeFile function without requiring preliminary conversion to URL format.

is this a problem only for writeFile? i expected this to happen for any FS API call..
also which error do you have? i assume the path sent to the tauri side is incorrect right?

[SRutile]

Only the writeFile function has this issue, as it uses request.body() to obtain the data. Normally, it should return Raw([]), but when there are Chinese characters or spaces, it returns Json(Object {"0": Number()}). To ensure it always returns data of the Raw type, I converted the path to URL format.

This will throw if provided path is something like this ./file or just file, because new URL() expects a valid URL e.g. <scheme>://<domain>

[SRutile]

I'm aware of this issue and appreciate you pointing it out. To resolve this, I decided to abandon using new URL() and instead used TextEncoder, adding decoding logic on the Rust side.

如果是mac的话，path没有file://协议开头，new URL会出错的，还要把path加上file
