> DataSourceResourceLoader corrupts UTF-8 encoded characters in template
> ----------------------------------------------------------------------
>
> Key: VELOCITY-880
> URL: https://issues.apache.org/jira/browse/VELOCITY-880
> Project: Velocity
> Issue Type: Bug
> Affects Versions: 2.1.x
> Environment: Oracle12c and HSQLDB 2.3.4, JDK 1.8
> Reporter: James R Doyle
> Attachments: project.tar.gz, velocity-880.patch
>
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> A long-withstanding bug in the DataSourceResourceLoader corrupts UTF-8
> templates retrieved from the database. The Unit Test suite for this resource
> loader has deficiencies that hide the bug.
> The cause of the problem is this:
> {code}
> InputStream rawStream = rs.getAsciiStream(templateColumn);
> The resolution of the problem is simply:
> Reader r = rs.getCharacterStream(templateColumn);
> InputStream rawStream = null;
> try {
> rawStream = IOUtils.toInputStream(IOUtils.toString(r),
> encoding);
> } catch (IOException ioe) {}
> {code}
> Once done, the test failure vanishes:
> org.junit.ComparisonFailure: Unicode test failed.
> Expected :The Euro Currency Symbol € is a two-byte UTF-8 encoded
> character.
> Actual :The Euro Currency Symbol ? is a two-byte UTF-8 encoded
> character.
> The bug was verified and the fix was tested against Oracle12c and HSQLDB
> 2.3.4 using a CLOB column to store the template data.
> The Unit Tests for this resource loader need attention.
> Please see VELOCITY-599 ; long standing problem, which has been erroneously
> marked as resolved but has been in the codebase for a long time.
