> I plan to do the following changes to UTF8Reader:
>  * Improve the error reporting when hitting a UTF8 decoding error (currently an UTFDataFormatException with no message). This might also lead to deleting one helper method for generating an exception (the one with no message).
>  * Improve error reporting for trying to use the reader after it has been closed (currently an IOException with no message).
>  * Remove trailing spaces, and add a few newlines here and there.
>  * Replace tabs in the file with spaces.
> Now, the last point can be discussed, but here are my arguments for doing it:
>  * The file now has a mix of tabs and spaces (but still more tabs).
>  * Spaces are the preferred/required method of indentation.
>  * I want to get it fixed before the branch is cut, which makes it easier to port fixes from trunk/10.3-NEXT to 10.3. If I don't make it for 10.3, I won't do it.
>  * I don't see it as very likely that we will back-port major fixes to this class on the 10.2 branch. If we have to, I will volunteer :)
>  * Since so much else of the Clob "infrastructure" has changed recently, this seems like a good time to do the clean-up.
> Please raise your concern as soon as possible if you want to veto these changes. 
> I do plan to commit them tomorrow.
