does Storage support reading/writing binary data?

Hello again!

Does the Storage module support reading/writing binary data?

• StorageFile does not (as it uses 0xFF for internal purposes)
  
• I do not want to use atob/btoa as these do not really support "chunking" (i.e., chunks read must always be of the same size as chunks written)
  
• if possible, I would like to read/write ArrayBuffers - is that possible?
  
  

(an alternative question could be: are strings in Bangle.js Unicode strings? or ASCII ones? if the latter, strings could be used instead of ArrayBuffers, making "binary" I/O just identical to "text" I/O)

Thanks in advance for your help!
