I have an iPhone app that gets push notifications from a Windows server as well as other data over HTTP, the data I get over HTTP looks good on the screen, but the push notification shows only questions marks, I tried encoding it as UTF-8, ASCII but still I get the question marks, my iPhone is configured to hebrew and i have a he.lproj file and no en file
does any one has an idea??
Got what was the bug, Im using a push notification server based on Moon-Apns and after checking in source code i found out that they are encoding the needed chars to UTF-8... but they dont use the string they encode to, they pass the original string to the apn, so i fixed it and now all is well, thank you all for trying to help me! if anyone need this fix ill be glad to point to it and give the code
It seems to me that your server side in encoding Hebrew incorrectly. Try to ensure that server response is correct. I had the same problem with Russian encoding, it was solved only when we set php response code to UTF-8 (not Latin1 as it was set by default).
Use nslog to see what data is receiving in pushnotification and appdelegate didreceive remote notification method, and if there is no data, then you have problem at server side that may be in correct parameter assigning to notification object
Make sure that the encoding on both the sending and receiving site is the same (e.g. UTF8).
For me specific help, your code is necessary.
If you are not able to print non-latin text with NSLog(), this question could probably help you.

I'm having problems displaying emojis in a UILabel.
in some cases, it even causes a crash when lay-outing the characters in the label.
these characters are returning from server as unicode, and are parsed with AFNetworking framework.
this is an example of how it is returned from the server (console logs):
\U05d4\U05d9\U05d9
i have tried different approaches, like lowercasing this to "\u05d4" or playing with the encoding of the string returning.
nothing seems to work.
i did managed to show a couple of emojis properly (which makes me think it maybe a server related issue?) - does the server needs to support sets of unicode characters so it can return it in the appropriate encoding? i'd be happy if someone could clarify this point for me. (btw, server is written in RubyOnRails i believe.)
should i parse the data with a different parser (SBJSON)? although switching the networking framework at this point would be impossible due to time and resources available..
what other options do i have?
Thanks
i think you should be able to just paste an emoji character in the code directly as a text.
I have an iPhone application in which I am sending text in an UITextview to a server through a web service. and in the next page I am displaying the list of comments from the server through the web service. Everything is working fine except when I insert emoji/emoticons in the UITextview.
The next page displays square boxes instead of some emoji character (not all).
I have noticed that:
Working: I have inserted one emoji character in UITextview from an emoji keyboard and printed its code in log, \u2601, and submitted this text to the server. In the next page I got the same unicode \u2601 and it's working fine. It shows me the emoji icon.
Not Working: Now I have inserted another emoji character in the UITextview from the emoji keyboard and printed its code in log, \ud83d\udc16, and submitted this text to the server. In the next page I got a unicode codepoint which is different from what I sent: \uf416. iPhone doesn't recognize this unicode so it gives me a square box.
So what is the problem here? It's not working only when the emoji character has a pair of unicode codepoints.
The database in which the comment is stored is MySQL version 5.5.
Why does the emoji character code pair change when retrieved from the server? How to decode the retrieved Unicode into its original form so iPhone can recognize it?
The character U+F416 is in one of the Private Use Areas (PUA).
Likely, some code on the way from the app to the database and back replaced the emoji with this character. This could be any of the components on this way, e.g. the client library tha you use to communicate with the service, the web service, the database interface, or the database itself. Try to tackle each of this layers individually, or follow the character through the layers to check whether it is still correct.
Thanx Mar Byers, You gave me hint. I have read what is Unicode planes and what is surrogates and how it works. I have found that that is no server problem actually, because my SQL server version is 5.5 that has character set uyf8mb4, i have used that set in Comments column.
Now the problem with SBJSON that i used in my app to decode json response geting from server.SBJSON decode that surrogate pair(UTF16 UTF16) in one unicode UTF16, and thats why the emoji with surrogate pair is not displayed. Apple introduce json library NSJSONSerialization for ios5 and later os. I used that library to decode json response and my code work like charm..:)

I have iPhone app that worked fine with SOAP and WSDL untill today. It suddenly started sending SOAP response with stripped end tag. for example
...../SOAP-ENV:Body></SOAP-ENV:Envelop
instead of
..../SOAP-ENV:Body></SOAP-ENV:Envelope>
Nothing have been changed from server. Any idea why i am getting this error
After spending 3 hours i got solution. Thought to share here if somebody else get this sort of problem.
It was due to weired characters. Windows automatically put some characters into soap file. So when it return response it counts no. of characters but because there are hidden BOM http://en.wikipedia.org/wiki/Byte_order_mark characters so it included them and sends actual response stripped.
So just find BOM and remove them and you will be fine
Thanks
I have a wordpress installation that clients can edit, all characters display ok. On the main homepage I query the same database for the same title and post content, but it doesn't display correctly - just a question mark
I have tried sending the utf8 headers manually, through htaccess and through meta tags. I have used SET name UTF8 (which turns the characters into the diamond symbol with a questionmark inside).
I genuinely cant figure out what it could be now and I really need these characters to display correctly.
Heres the homepage, you can see in the Sounddhism 6 preview that there are lots of question marks, if you click on it you will see what they are meant to look like
http://nottingham.subverb.net
I have passed it through the validator and it gives me this error:
Sorry, I am unable to validate this document because on line 373 it contained one or more bytes that I cannot interpret as utf-8 (in other words, the bytes found are not valid values in the specified Character Encoding). Please check both the content of the file and the character encoding indication.
The error was: utf8 "\xA0" does not map to Unicode
Which, i appreciate is supposed to help me, but I don't know what to do about it. Especially since that line, the letter generating the error is supposed to be a space and is AFTER the offending question marks.
Can anyone help?
Compare the encoding of both the back-end scripts in Wordpress and also your homepage script. If you're using IE, right-click the page and check the encoding. Sometimes it's set to "Auto-detect" and IE will often detect a different encoding for different pages, causing strange issues like this.
If you're not using IE, try using a tool like Fiddler to see exactly what encoding (and what bytes are being sent back and forth both in the back-end and your homepage script.
If forcing UTF-8 on your homepage script doesn't work, I would guess that the back-end is not using UTF-8.
I'm writing server-side programs in PHP for an iPhone app. And I have no iPhone. :P
The iPhone app requests XML files from the site whenever a user runs the iPhone app. You may visit http://www.appvee.com/iphone/ads or http://www.appvee.com/iphone/latest for the XML files.
And a message box will show up with the following error messages:
"Web Site Error
Conversion of data failed. The file is not UTF-8, or in the encoding specified in XML header if XML.
"
Maybe I must add header("Content-type: text/xml"); at the beginning of the PHP files? I didn't add this line and it worked well before.
Any help is greatly appreciated.
I agree with ceejayoz, looks like this is a special characters issue.
I would suggest using the htmlentities method to encode the data in the xml file.
It might be the unescaped special character (looks like it's supposed to be a curly apostrophe) in the 'latest' XML. (in the line that goes "Find out information about what[THIS IS THE CHARACTER]s around you and how...")
Does adding an XML content type header resolve the issue? You ask it if's necessary but give no indication if it helps or not.
