android - Motorola MC40 doesn't recognize cyrillic symbols at DataMatrix code -


i'm using motorola mc40 on android emdk. when scan data matrix code cyrillic symbols capital "О" (u041e), function scandata.getdata() returning string character "�" (code 65533).

when use software tool i-nigma sdk, return string of charracters in 1251 codepage , can recognize it.

could me read datamatrix barcodes emdk?

image:

datamatrix barcode string: #1@#ОС@#0700022520

coded string: #1@#ОС@#0700022520

i-nigma decoded sequence of bytes hex: [23 31 40 23 ce d1 40 23 30 37 30 30 30 32 32 35 32 30]

mc40 decoded string: #1@#��@#0700022520

emdk version: 3.1 os version: 4.1.1

as far understand need sequence of read bytes before converted string, or set code page of source data converter.

zebra's emdk v4.0 released january 2016 introduce new method in barcode api scan raw data: getrawdata().

as example can use following code in barcodesample1 can find on github

@override public void ondata(scandatacollection scandatacollection) {  if ((scandatacollection != null) &&     (scandatacollection.getresult() == scannerresults.success)) {    arraylist <scandata> scandata = scandatacollection.getscandata();   for(scandata data : scandata) {       //barcode label type       string datastring = "label type: " + data.getlabeltype() + "\n" ;       //barcode data encoded string       datastring += "encoded data size: " + data.getdata().length() +                     " string: " + data.getdata() + "\n";       //barcode data raw data       datastring += "raw data size: " + data.getrawdata().length +                      " (hex): " + bytestohexstring(data.getrawdata());        new asyncdataupdate().execute(datastring);     }   }  }

where bytestohexstring() simple helper function:

    public static string bytestohexstring(byte[] bytes){       stringbuilder sb = new stringbuilder();      for(byte b : bytes){         sb.append(string.format("%02x ", b&0xff));         }     return sb.tostring();    }

in case getrawdata returns byte[] containing barcode's raw data.

html - Outlook 2010 Anchor (url/address/link) -

i'm trying link specific pdf page msoutlook'10 or msword'10, #page=... anchor particularly useful , works fine elsewhere. unfortunately when click [ctr-k] in outlook or winword, links re-formatted assuming unc path. pdf file located on shared drive. using "file:" prefix links open pdf in adobe reader (outside of browser), , "http:" open inside browser. issue seem need open in browser "file:" prefix in order anchor work. know anchors work inside browser. outlook uses windows/explorer default program (based on file extension) seems open in adobe reader neglecting anchor. is aware of solution, link specific page or bookmark of shared-pdf ms outlook and/or winword link? common references: mailermailer.com/...anchor-tags-html-emails campaignmonitor.com/...anchor-links-in-email-newsletters/ stackoverflow.com/...anchor-in-pdf-document

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
