Hello,  
I'm trying to install OpenZeppelin contracts.

But each time I have this error :

```auto
Sorry, name can only contain URL-friendly characters.

```

#### 🔢 Code to reproduce

In my Terminal, here is what I did :

```auto
truffle init

```

Then

```auto
npm init

```

And :

```auto
npm install @openzeppelin/contracts

```

I found this line in the docs (in "Overview").

#### 💻 Environment

Windows 10  
Truffle v5.4.11 (core: 5.4.11)  
Solidity v0.5.16 (solc-js)  
Node v14.17.6  
Web3.js v1.5.2

Seems to be working fine for me 🤔 ...

But this is def. an npm installation error.
