docs: Uploads a file from a string using the specified encoding. If the file already exists on the service, it will be
  overwritten.
  
  @param content
  A <code>String</code> which represents the content that will be uploaded to the file.
  @param charsetName
  A <code>String</code> which represents the name of the charset to use to encode the content.
  If null, the platform's default encoding is used.
  @param accessCondition
  An {@link AccessCondition} object that represents the access conditions for the file.
  @param options
  A {@link FileRequestOptions} object that specifies any additional options for the request. Specifying
  <code>null</code> will use the default request options from the associated service client (
  {@link CloudFileClient}).
  @param opContext
  An {@link OperationContext} object that represents the context for the current operation. This object
  is used to track requests to the storage service, and to provide additional runtime information about
  the operation.
  
  @throws StorageException
  If a storage service error occurred.
  @throws IOException
  @throws URISyntaxException
