+### The {{Blob/text()}} method ### {#text-method-algo}
+
+The <dfn method for=Blob>text()</dfn> method, when invoked, must run these steps:
+
+1. Let |stream| be the result of calling [=get stream=] on the [=context object=].
+1. Let |reader| be the result of [=get a reader|getting a reader=] from |stream|.
+   If that threw an exception, return a new promise rejected with that exception.
+1. Let |promise| be the result of [=read all bytes|reading all bytes=] from |stream| with |reader|.
+1. Return the result of transforming |promise| by a fulfillment handler that returns the result of
+   running [=UTF-8 decode=] on its first argument.
+
+Note: This is different from the behavior of {{FileReader/readAsText()}} to align better
+with the behavior of {{Body/text()|Fetch's text()}}. Specifically this method will always
+use UTF-8 as encoding, while {{FileReader}} can use a different encoding depending on
+the blob's type and passed in encoding name.
