Unhandled exception in method ReadLink(string path)

Hello.

Unhandled exception throw in Avalonia.FreeDesktop.NativeMethods.ReadLink(String path).

“The output byte buffer is too small to contain the encoded data, encoding ‘Unicode (UTF-8)’ fallback ‘System.Text.EncoderReplacementFallback’.”

Input parameter: “/dev/disk/by-label/Зарезервировано\x20системой”

Maybe instead of var symlinkMaxSize = Encoding.ASCII.GetMaxByteCount(path.Length);

use

var symlinkMaxSize = Encoding.UTF8.GetMaxByteCount(path.Length);

Thanks.

@jmacato you should use realpath instead since it already implements proper path resolving logic.

Just declare it as

        [DllImport("libc", SetLastError = true)]
        private static IntPtr realpath(string path, IntPtr unused);
        [DllImport("libc"]
        private static void free(IntPtr mem);

var resolvedPtr = realpath(pathString, IntPtr.Zero);
if(resolvedPtr == IntPtr.Zero)
    throw new Win32Exception();
var rv = Marshal.PtrToStringAnsi(resolvedPtr);
free(resolvedPtr)
return rv;

Marshaller will do all of UTF8 conversions automatically without extra manual work that you were doing incorrectly anyway
