> On other platforms like Windows and Linux, the `\n`, `\r` and `\t` characters are ignored when drawing text to a `Graphics2D` object. On macOS this is not currently the case.
> 
> See, for example, `CMap.getControlCodeGlyph(int, boolean)` or `RasterPrinterJob.removeControlChars(String)`.
> 
> This bug was found while running `test/jdk/java/awt/print/PrinterJob/PrintTextTest.java` on macOS.
> 
> The new test class passes on Linux, Windows and macOS.
