How can one troubleshoot and resolve issues related to font rendering and table formatting when converting files using external applications in PHP?

Issue: When converting files using external applications in PHP, font rendering and table formatting issues may arise. To troubleshoot and resolve these problems, ensure that the fonts used in the source file are available on the server where the conversion is taking place. Additionally, adjust the CSS styles for table formatting to ensure proper rendering in the output file. PHP Code Snippet: 

// Set the path to the source file
$sourceFile = 'path/to/source/file.docx';

// Set the path to the output file
$outputFile = 'path/to/output/file.pdf';

// Command to convert the source file to PDF using LibreOffice
$cmd = 'libreoffice --headless --convert-to pdf --outdir ' . dirname($outputFile) . ' ' . $sourceFile;

// Execute the command
exec($cmd);

// Output success message or handle any errors
echo 'File converted successfully!';
