Console output doesn't use unicode · Issue #5401 · pmd/pmd · GitHub

Affects PMD Version: 7.8.0

Description:

pmd --version doesn't look nice. But if you have a custom ruleset with custom rule messages, that use UTF-8, then the output on the console is broken.

Eg. ruleset:

<?xml version="1.0" encoding="utf-8"?>

<ruleset name="Custom Rules"
    xmlns="http://pmd.sourceforge.net/ruleset/2.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://pmd.sourceforge.net/ruleset/2.0.0 https://pmd.sourceforge.io/ruleset_2_0_0.xsd">

    <description>
        My custom rules
    </description>

    <rule ref="category/java/bestpractices.xml/AbstractClassWithoutAbstractMethod" message="This is a Ümlaut." />

</ruleset>

When running PMD in a windows command prompt, the output looks like this:

> pmd --version

The correct output after executing chcp 65001 is:

> pmd --version
  ████                            ████

Note, that redirecting the output (using > report.xml) or just writing the report into a file using -r report.xml produces correct output. It seems to be only the display in the console window.
