java - PDFBox:AAAAAD+FreeSerifBold 字体中没有 U+0054 的字形

Question

我的 PDFBox 抛出以下错误:AAAAAD+FreeSerifBold 字体中没有 U+0054 的字形。我在 stackoverflow 上发现了几个类似的线程，但我无法通过它们解决我的问题。

我的代码类似于代码示例:

    public QuoteWorkerPdf() throws IOException {
    // Create PDF with one blank page
    document = PDDocument.load(
            getClass().getResourceAsStream("data/quote_template.pdf"));
    page = (PDPage) document.getDocumentCatalog().getPages().get(0);
    printable = new PDFPrintable(document);

    // get the document catalog
    PDAcroForm acroForm = document.getDocumentCatalog().getAcroForm();

    // as there might not be an AcroForm entry a null check is necessary
    if (acroForm != null)
    {
        // Retrieve an individual field and set its value.
        PDTextField field = (PDTextField) acroForm.getField( "q2_quotationPrepared" );
        field.setValue("TextEntry");

        // If a field is nested within the form tree a fully qualified name
        // might be provided to access the field.
        //field = (PDTextField) acroForm.getField( "fieldsContainer.nestedSampleField" );
        //field.setValue("Text Entry");
    }

    // Save and close the filled out form.
    document.save("target/FillFormField.pdf");
}

U+0054 是“T”，它是字符串的第一个字母。对于 pdf 表单创建，我使用 www.jotform.com。

有人知道我该如何解决这个问题吗？

此代码是根据您的文件定制的。它更改默认外观字符串以使用不同的字体。另请参阅this answer这有些相关，但更普遍。

您的输入文件的问题是字段中使用的字体是子集，因此它不具有您期望的所有字形。

PDDocument doc = PDDocument.load(new File("82667884384374 (1).pdf"));
PDAcroForm acroForm = doc.getDocumentCatalog().getAcroForm();
PDTextField field = (PDTextField) acroForm.getField("q2_quotationPrepared");
COSName helvName = acroForm.getDefaultResources().add(PDType1Font.HELVETICA); // use different font if you want. Do not subset!
field.setDefaultAppearance("/" + helvName.getName() + " 10 Tf 0 g"); // modifies your existing DA string
field.setValue("TextEntry");        
doc.save(new File("82667884384374 (1)-new.pdf"));
doc.close();
