Space character being ignored

[AtlasAutocode]

Describe the bug
On Windows Desktop, an instance of the Text class containing a single space character is not output to PDF.
Is there some setting that I need to change?

To Reproduce
Code snippet to reproduce the behavior:

    doc.addPage(
      pw.MultiPage(
        build: (pw.Context context) => [
          pw.Partitions(
            children: [
              pw.Partition(
                child: pw.Row ( children: [
  pw.Text ( 'pre'),
  pw.Text (' '),    // space character
  pw.Text ( 'post'),
]),
    )])]));

Expected behavior
Text with space pre post

Actual behavior
Text space missing prepost
