I am encountering a problem concerning text-encoding on iPhone. I retrieve japanese characters from a sqlite database. So I get character like that ( their ASCII representation here : "& #25104;& #12395;& #12424;& #12427;" )
When I display these characters on a WebView, my japanese characters are well displayed. But when I try to display them on a UILabel, the ASCII representation is displayed rather than the japanese one.
I retrieve the text data from the database with the following function :
NSString *watchText = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 0)];
If anyone has an idea...
That's because what you have is not an "ASCII representation". Those ("成による") are known as XML or HTML character entity references. As such, they only work if you parse them in an HTML context (like a web view).
What you need to do is either use a UIWebView for your labels, or parse the character entity references to turn them in to a normal NSString.

I am using API to get data from CMS, we are displaying text what user has entered into CMS,
But my problem is when user enter some special character into CMS,I am not able to get those text on iphone side
Here is the link of text what user has entered in wall description
We are using json web service, they are encode string to utf-8 so my json string will be
The word 'stop' isn\u0092t in your vocabulary. Run a marathon in 4.5 hours or less.
The utf character \u0092 is a special character we need to display same in shown in above image
NOTE:
1)if we pass string without encoding to utf-8 in webservice,I am getting whole string as null .
2)I have try with [NSString stringWithCString:[textFromCms cStringUsingEncoding:NSISOLatin1StringEncoding] encoding:NSUTF8StringEncoding];
where textFromCms is text I got from cms as show above.
3)I also try without any conversation/encoding ….it ignore the special character
4)also try with base64 but did not help that also.
Any help would be so appreciated.
The CMS apparently uses windows-1252, not UTF-8. The curly apostrophe is 92 (hex) in windows-1252, U+2019 in Unicode, so when properly encoded into JSON, it should be \2019.
I have a list of several locations, some of them containing the letters æ, Æ, ø, Ø, å and Å.
From the webservice I'm using, the letters comes out as "ø ;" "Å ;" etc.
When I download the feed from the webservice, I use UTF-8 encoding.
How can I decode the occurences of these characters?
Thanks!
There is no standard way, to make it simple write your own custom method (or NSString extension) and do this :
string = [string stringByReplacingOccurrencesOfString:#"&" withString:#"&"];
If your webservice is using utf8 and if you decode the data with [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding], all should be ok.
A NSString category called "GTMNSString+HTML" written by Google works perfectly for me. Check it out here: https://gist.github.com/takuma104/ntlniph/blob/master/gtm/Foundation/GTMNSString+HTML.h & here: https://gist.github.com/takuma104/ntlniph/blob/master/gtm/Foundation/GTMNSString+HTML.m
I have a problem of string encoding. Actually I have a application, which is in 5 languages swedish, norwegian, english, finnish and danish. In one of section of my app, I get the review of user so it's possible to come in different language format like the word in swedish nämndes.
Now the problem is i get the response of review in JSOn format and the swedish character ä came as &a and it print as &a. i want to print as ä format. same in all language character problem.
Please help me...
I do something like this when Im requesting xml data from myserver.
NSString *responseString = [request responseString]; //Pass request text from server over to NSString
NSData *capturedResponseData = [responseString dataUsingEncoding:NSUTF8StringEncoding];
Hope it helps.
Solution finally i change the web service character encoding. The web service Change the special word into UTF8 style encoding like /U00.. When we display in text or label it automatically converted and display specific word.
I have a little app which lists the names of certain people from around the world, and some of those names use characters that are not normal ASCII characters, like DÌaz, or ThÈrËse for example.
The strings show up in Xcode just fine, but when I put them in a UILabel, they behave unexpectedly.
My question is: Is there a way to set up a UILabel to to take the exact string in Xcode, and display it properly, even if it is a UTF-8 character (or any other character encoding for that matter)?
UIKit fully supports unicode, your problem is most likely the encoding of the source file. You can set that in the inspector (Xcode 4: ⌘⌥1) under "Text Settings". Make sure it is UTF-8 as well.
Alternative: Use unicode escapes like #"\u2605" (should display ★).
Try to encode the String:
NSString *s = [NSString stringWithCString:value encoding:NSASCIIStringEncoding];
I have implementing pdf parsing in which i have parsed pdf and fetch the all text but it disply junks characters so i want to convert in to utf string.How it possible please help me for this question.
First, you need to find out which encoding is currently used for the text. I guess it's ISO-8859-1, aka Latin-1 or it's variant ISO-8859-15, aka Latin-15.
As soon as know that it's a piece of cake. You haven't said in which container you got the text, e.g. whether it's stored in a C string or NSData.
Let's assume you got a C string. In that case you would do:
myString = [[NSString alloc] initWithBytes:myCString
length:strlen(myCString)
encoding:NSISOLatin1StringEncoding];
If you got a NSData, you would use the initWithData:encoding: initializer instead. That's all you need to do, as according to Apple's documentation, "A string object presents itself as an array of Unicode characters". If you need a UTF8-encoded C string, you can then query it via:
myUTF8CString = [myString UTF8String];
There's also dataUsingEncoding: to get a NSData object instead of a C string.
Have a look at the NSString class reference and the NSStringEncoding constants.
