In this case a two-file solution, one JSON and one raw binary, would probably be the most efficient. I understand the desire to work with a single file, though. One thing we could do is add something to the DataView class for reading/writing strings to/from an ArrayBuffer using a given format; that might be a fairly natural fit for that type of functionality (which has been requested in other contexts as well -- e.g. reading a binary file that has an embedded string that refers to a texture file or something).
The author of node.js raised the issue of encoding and decoding typed
arrays using multiple character encodings a few months ago. See
and follow-ups on the thread. To avoid making the Typed Array
specification too monolithic I think it would be best to factor
conversions to and from strings into a separate specification. However
I would personally be very happy to help implement any such
specification in WebKit.
Would anybody be willing to step up and draft such a spec?
