The codePointOffset is negative and the subsequence of the string before the index has fewer code points than the absolute value of codePointOffset.The codePointOffset is positive and the subsequence of the string starting from the index has fewer code points than codePointOffset.The index is greater than the length of the string. setLatestEventInfo(TermService,CharSequence,CharSequence,PendingIntent)API Level 11Android 2.3.3setLatestEventInfo().Note: The offsetB圜odePoints() method throws the IndexOutOfBoundsException if it satisfies any of the following conditions: The offsetB圜odePoints() method returns the index within this string that is the offset from the given index by codePointOffset code points. codePointOffset: The offset in code points.

The offsetB圜odePoints() method can be declared as shown in the code below: public int offsetB圜odePoints(int index, int codePointOffset) No exception should be reported.The offsetB圜odePoints() method in Java is used to return the index within a string that is the offset from the given index by codePointOffset code points.

Run your java application selecting Unicode data.

Verify that inserted data were converted to UTF-8 during insert:.

If you prepare data yourself using some editor please check the documentation for your editor to find out how to set up the codepage for data being prepared by the editor. One of the way to determine the codepage for your data can be found here. Change the locale to one that matching codepage of data to be inserted:Įxport locale=en_us.Delete all rows with incorrect Unicode codepoints from the test table:.Caught by java.io.CharConversionException. This is expected because the table contains invalid UTF-8 data:Įrror executing Select SQL statement. When selecting from a column using the JDBC application, the following error will occur.So these three rows in the table contain invalid characters in UTF-8.

However, the UTF-8 representation of those characters are: 0x'C383' for 'Ã', 0x'C2B3' for '³', and 0x'C2A9' for '©'.

By running the following statement, you can see that all INSERT statements caused only one byte to be inserted into the table:.

Insert the non-ASCII characters 'Ã', '³', '©' which have codepoint 0x'C3', 0x'B3',0x'A9' in codepage 819 into the table:.

Create a table that holds character data:.

To force codepage conversion during insert from the CLP make sure that the operating system codepage is non-Unicode and matching to the codepage of data when you insert data to Unicode database from non-Unicode data source.Īn example problem scenario is as follows:ĬREATE DATABASE USING CODESET utf-8 TERRITORY US If you see only 1 byte per non-ASCII characters then you need to force the database conversion during insert from CLP to UTF-8 database. Please verify the codepoints for non-ASCII characters that you try to insert. To verify the encoding for data to be inserted you can use any editor that shows hex representation of characters.

If operating system and database codepage both are UTF-8, but the data to be inserted is not Unicode, then data in the database might have incorrect codepoints (not-Unicode) and the above error will be a result during data retrieval. During an insert of data using CLP characters, they do not go through codepage conversion.
