求助：使用Bootstrap Table+pdfmake导出PDF不支持土耳其字符

Hey, I’ve dealt with exactly this problem before when working with non-Latin characters like Turkish in Bootstrap Table’s PDF exports. The good news is there are a few straightforward fixes that usually resolve the weird character display. Let’s break them down:

• Replace the default PDF font with a Turkish character-compatible one
  Bootstrap Table’s PDF export (powered by pdfmake) typically uses a default font that doesn’t support extended Latin characters like ğ, ş, ı, ö, and ü. Swap it out for a font that does, like DejaVu Sans. Here’s how to adjust your table’s export configuration:

  $('#your-table-id').bootstrapTable({
    exportOptions: {
      pdfmake: {
        enabled: true,
        docDefinition: {
          defaultStyle: {
            font: 'DejaVuSans'
          }
        }
      }
    }
  });
  

  Make sure you’ve included the pdfmake Virtual File System (VFS) font bundle that includes DejaVu Sans. If you’re hosting files locally, add the vfs_fonts.js file to your project and reference it in your HTML – this bundle preloads the necessary font files for pdfmake to use.

• Confirm UTF-8 encoding across your stack
  Double-check that your HTML page has the UTF-8 meta tag set:

  <meta charset="UTF-8">
  

  Also ensure your backend is returning data in UTF-8 encoding. If the data itself is corrupted before it reaches the table, even the right font won’t fix the display.

• Update your dependencies
  Outdated versions of Bootstrap Table or pdfmake might have known encoding bugs. Upgrade to the latest stable versions of both libraries – this often resolves edge-case character rendering issues without extra configuration.

• Tweak special character handling (if needed)
  If you still see oddities with specific characters, you can explicitly map them in your PDF definition, though this is rarely necessary if you’re using a compatible font. For example, you could add a custom style for elements containing Turkish characters, but the font swap should cover most cases.

Give these steps a shot – the font replacement is almost always the fix that gets Turkish characters displaying correctly in your exported PDFs. Let me know if you hit any snags!
