String Decoding in Golang

Try this:

package main

import (
    "bytes"
    "encoding/binary"
    "log"
)

type UnpackedThing struct {
    First  uint32
    Second uint32
    Third  uint32

    Fourth float32
    Fifth  float32
}

func main() {
    input := bytes.NewBufferString("]\x00\x00@\x00\x8C\xD2\x00\x00\x00\x00\x00\x00\x00\x00h.\x9FAjK\x8FG\xC0T\x87UX\xA1CH\xB7\x80\x82}\xBB\xF9\x8F\xBAcqF{\xE31/Zx\xC0\x04\xFF\b\xA0\xBD\a\x9E\x0F\x14c+\b\xD3\xE8\xE1\xC2\x1C7\xBCmd/j\xC1H\x191~\x91F\b5-\x8A\x9F(\\\xF1\x16/\x0F\xEA\xD9\x94rV\xEC\xBB\xCB\x12qJ\x05\b\x04 {R\xB8\xA4\xA9\xD0)v\x97<\xCA\x92\xB6U\b)\x1D\x1D\xF1\x00\xE4U\x8DB\x16/v\xEC[bLTW\xB2\xFB\x0F\x91\x05\xAA\x9C\xBD\x8E\x1A\xFB\xDFUJ\xB8\xDE\xF5m\xC8Z\xC1\v\\|\r;\xB6\xE6\xA6\x13o\x91\xE1\xBA\x9An\x8B\x01W\xB9\"\x12+\x9B[\xC7\xCD\xC2O+\f^|\xE1G\x86.%m\xB2x\xF1j\x1B\"\xE41Bu_\x16J\xE4M\x7F\xC5U[\xB9\xD0\xC7\xECu\xE53\xB4)\xD5\x80|\xB7.\xD2\f\xF3\x16\x8B\xE3\x13\x81\x02:5\x88\x0F")
    var unpacked UnpackedThing

    err := binary.Read(input, binary.LittleEndian, &unpacked)
    if err != nil {
        log.Fatal(err)
    }

    log.Printf("[%d, %d, %d, %f, %f]\n",
        unpacked.First, unpacked.Second, unpacked.Third, unpacked.Fourth, unpacked.Fifth)
}

We're creating a struct that properly represents the binary format, then using binary.Read() to read our bytes into this struct. One thing to note is that golang's strings don't understand \e, so it must be converted to \x1b.
