[Glass] What is this chunk of memory prefixing my bytearray?

Hi guys,

I found something weird today. If you inspect this:

  ( ServerFileDirectory on: '/dev/random') directoryEntry readStreamDo:
[ :s |
s binary.
(s next: 20) asByteArray ]
You get something like:

  Ý5öyoÓT¾àiwð¯p… óž“è( 221, 53, 246, 121, 111, 211, 84, 190, 224, 105,
119, 240, 175, 112, 133, 17, 243, 158, 147, 232)

If you inspect it, the ByteArray is correctly size 20, and each element
seems correct. But what are those weird characters I see in the
inspector/print?

Well, they look like they're the byte array printed as a string of characters. Certainly the second byte, 53, is the codepoint of $5.
