/**
 * Reserved URL characters must be properly escaped for Storage services like Blob or File.
 *
 * ## URL encode and escape strategy for JS SDKs
 *
 * When customers pass a URL string into XxxClient classes constructors, the URL string may already be URL encoded or not.
 * But before sending to Azure Storage server, the URL must be encoded. However, it's hard for a SDK to guess whether the URL
 * string has been encoded or not. We have 2 potential strategies, and chose strategy two for the XxxClient constructors.
 *
 * ### Strategy One: Assume the customer URL string is not encoded, and always encode URL string in SDK.
 *
 * This is what legacy V2 SDK does, simple and works for most of the cases.
 * - When customer URL string is "http://account.blob.core.windows.net/con/b:",
 *   SDK will encode it to "http://account.blob.core.windows.net/con/b%3A" and send to server. A blob named "b:" will be created.
 * - When customer URL string is "http://account.blob.core.windows.net/con/b%3A",
 *   SDK will encode it to "http://account.blob.core.windows.net/con/b%253A" and send to server. A blob named "b%3A" will be created.
 *
 * But this strategy will make it not possible to create a blob with "?" in it's name. Because when customer URL string is
 * "http://account.blob.core.windows.net/con/blob?name", the "?name" will be treated as URL paramter instead of blob name.
 * If customer URL string is "http://account.blob.core.windows.net/con/blob%3Fname", a blob named "blob%3Fname" will be created.
 * V2 SDK doesn't have this issue because it doesn't allow customer pass in a full URL, it accepts a separate blob name and encodeURIComponent for it.
 * We cannot accept a SDK cannot create a blob name with "?". So we implement strategy two:
 *
 * ### Strategy Two: SDK doesn't assume the URL has been encoded or not. It will just escape the special characters.
 *
 * This is what V10 Blob Go SDK does. It accepts a URL type in Go, and call url.EscapedPath() to escape the special chars unescaped.
 * - When customer URL string is "http://account.blob.core.windows.net/con/b:",
 *   SDK will escape ":" like "http://account.blob.core.windows.net/con/b%3A" and send to server. A blob named "b:" will be created.
 * - When customer URL string is "http://account.blob.core.windows.net/con/b%3A",
 *   There is no special characters, so send "http://account.blob.core.windows.net/con/b%3A" to server. A blob named "b:" will be created.
 * - When customer URL string is "http://account.blob.core.windows.net/con/b%253A",
 *   There is no special characters, so send "http://account.blob.core.windows.net/con/b%253A" to server. A blob named "b%3A" will be created.
 *
 * This strategy gives us flexibility to create with any special characters. But "%" will be treated as a special characters, if the URL string
 * is not encoded, there shouldn't a "%" in the URL string, otherwise the URL is not a valid URL.
 * If customer needs to create a blob with "%" in it's blob name, use "%25" instead of "%". Just like above 3rd sample.
 * And following URL strings are invalid:
 * - "http://account.blob.core.windows.net/con/b%"
 * - "http://account.blob.core.windows.net/con/b%2"
 * - "http://account.blob.core.windows.net/con/b%G"
 *
 * Another special character is "?", use "%2F" to represent a blob name with "?" in a URL string.
 *
 * ### Strategy for containerName, blobName or other specific XXXName parameters in methods such as `containerClient.getBlobClient(blobName)`
 *
 * We will apply strategy one, and call encodeURIComponent for these parameters like blobName. Because what customers passes in is a plain name instead of a URL.
