Bug? HTTP Utils GetString issue

[qsrtech]

Using pretty much the same code in b4a but some of my http (html) results are throwing an error in b4i/ipad

Here is the error msg, hopefully something can be made from it to determine how to resolve. I did test directly loading into the webview the links that failed using httpjob.download2 and they seem to work without any issue. Again this works flawlessly in b4a's httpjob.download2. I actually even tried to replace the spaces in the link with "%20" and it returns no data at all.

Error occurred on line: 100 (httpjob)
Error decoding data as string.

Can you post the relevant code and if possible the link you are downloading?

 

[qsrtech]

try this line in your httputils example

job1.Download2("http://www.qsrtechnologies.com/requestdata.asp", Array As String("qry", "EXECUTE dbo.httptest 1"))

 

[Erel]

This is not a bug.
Job.GetString assumes that the string is encoded with UTF8. This is not the case here. I'm not sure which encoding is used however Windows-1252 works fine:

Job.GetString2("Windows-1252")

 

[qsrtech]

Ok, but that doesn't explain why it works fine on b4a 100%, and about 90% of the other "results" do work on b4i.

 

[Erel]

The decoding will only fail when there is one or more "invalid" characters. Android replaces the invalid character with a question mark or some other character. iOS throws an exception in this case (which is probably better as it allows you to fix the mistake).

Ahhh. I think i understand the situation now. I recall the funny question symbol now in android. Some of the "data" uses an (R) symbol (registered trademark) which must not be utf8 compatible. I think i prefer the android solution so it doesn’t break code. Then again i prefer android over apple.

Thanks for your help.
