is it possible to get utf8arrary from blobstorage in client

Question

I use SAS to access files. So i can get the files’ content by send a request.

But the problem is that i need to change the file’s encoding to SJIS.

so i’m trying to use Encoding.convert(), according to this (https://github.com/polygonplanet/encoding.js/blob/master/README_ja.md)

After this I’m going to use

URL.createObjectURL(new Blob([sjiscontent], {type: "text.plain"}))

But I don’t know how to convert my blobs’ string context to a sjis utf8arrary properly.

Yes you can. have a look at this: https://stackoverflow.com/questions/17191945/conversion-between-utf-8-arraybuffer-and-string — Software Person, Aug 27 '19 at 13:58
I will try it. Is it the only way to do it? if the blob is large, will it take to much time? — Jeff_hu, Aug 27 '19 at 23:02

Try to use the Streaming APIs of iconv-lite and request node packages to convert the content encoding in a stream.

For example, you have a blob url with SAS token.

var request = require('request');
var iconv = require('iconv-lite');
request('<a blob url with sas token>')
    .pipe(iconv.decodeStream('UTF-8'))
    .pipe(iconv.encodeStream('shift_jis'))
    .pipe(fs.createWriteStream('<your local file path>'))

The iconv-lite package supports Shift_JIS (SJIS) encoding.

But I'm not using nodejs. How could I use by javascript? – Jeff_hu Sep 06 '19 at 03:26 — Jeff_hu, Sep 06 '19 at 03:26
