I have a following code that encodes parameters with `AbiCoder`

```javascript
const token = IERC20MetadataFactory.connect(l1TokenAddress, provider);

const name = await token.name(); // Crown
const symbol = await token.symbol(); // Crown
const decimals = await token.decimals(); // 18

 const coder = new AbiCoder();

 const nameBytes = coder.encode(['string'], [name]);
 const symbolBytes = coder.encode(['string'], [symbol]);
 const decimalsBytes = coder.encode(['uint256'], [decimals]);

 return coder.encode(['bytes', 'bytes', 'bytes'], [nameBytes, symbolBytes, decimalsBytes]);
```

I am trying to achieve same result using `geth` library. I tried to create dummy ABI definition with 3 parameters in order to use `abi.Pack` function:

```go
const AbiDefinition = `[
	{
		"constant": true,
		"inputs": [
			{
				"name": "name",
				"type": "string"
			},
			{
				"name": "symbol",
				"type": "string"
			},
			{
				"name": "decimals",
				"type": "uint256"
			}
		],
		"name": "token",
		"outputs": [
				{
					"name": "",
					"type": "bool"
				}
			],
		"payable": false,
		"stateMutability": "view",
		"type": "constructor"
	}
]`


token, _ := erc20.NewIERC20(l1TokenAddress, backend)

name, _ := token.Name(nil)
symbol, _ := token.Symbol(nil)
decimals, _ := token.Decimals(nil)

bridgeDataAbi, err := abi.JSON(strings.NewReader(AbiDefinition))	
return bridgeDataAbi.Pack("", name, symbol, big.NewInt(int64(decimals)))
```

The results are no the same and I am having trouble to make them same.

Result from `ethers.AbiCoder`
