### Question:
PDFEmbeddedFileAttachment extends PDFExtensionAttachment { public String getFilename() { return filename; } PDFEmbeddedFileAttachment();  PDFEmbeddedFileAttachment(String filename, String src, String desc); String getFilename(); String getUnicodeFilename(); void setFilename(String name); String getDesc(); void setDesc(String desc); String getSrc(); void setSrc(String src); String getCategory(); String toString(); void toSAX(ContentHandler handler);  }### Answer:
@Test public void testGetFilename() { String germanAe = "\u00E4"; String unicodeFilename = "t" + germanAe + "st"; String src = "src"; String desc = "desc"; PDFEmbeddedFileAttachment fileAtt = new PDFEmbeddedFileAttachment(unicodeFilename, src, desc); assertEquals(fileAtt.getUnicodeFilename(), unicodeFilename); assertFalse(fileAtt.getFilename().contains(germanAe)); assertEquals(fileAtt.getSrc(), src); assertEquals(fileAtt.getDesc(), desc); }
