If for whatever reason you're unsatisfied with the built-in PDF exporter (File > Create PDF), there are a number of other methods you can use to output to PDF.
On Windows, there are a number of both freeware and commercial "PDF printers", which are essentially virtual printers that appear in the device list under File > Print, but output instead to a PDF file.
As of Windows 10, the system print dialog has introduced the capability to produce a PDF file directly.
On Mac, PDF output is available from the system print dialog.
Most Linux distributions have the capability to print to PDF as well (or to PostScript, which can be converted to PDF using ps2pdf).Tags: pdf, unicode
