reading large files with readArrayBuffer

hi,

i'm trying to read a large file (200kb).
(i just tested on the emulator and not the watch.)

using : let a = require("Storage").readArrayBuffer("test.map");
it loads but a.length is equal to 22053.

if i try let a = require("Storage").read("test.map", 0, 200000);
it seems to work but i get a string and i'd rather like to turn my arraybuffer into various arrays.

is there a size limit on readArrayBuffer and is there a reason for it ? do you know any kind of workaround i could use ?

thanks.
