Hello
I don't know how to make this with a command line, but you may read your
ASCII file, then use the menu File->Save Data, select the VTK file type,
and you will have a popup window with some options:
- Data mode: ascii, binary or appended (default).
- Compressor: None (default) or Zlib
May be this could be automated with a Python script. Browse the mailing
list: there are several subject about converting ascii to binary.
Also you make look here for Python vtk writers :

Hi Richard,
Thank you for your feedback. While we are hoping that Paraview
developers resolve this problem and accomplish a usable Tecplot
reader, I may rewrite a code to output my data as legacy .vtk ASCII files.
May I ask you a question? it is probably simple: how to convert a
legacy .vtk ASCII file to a binary file. Tecplot provides such a
command line tool, preplot, which compresses data greatly before
loading into Tecplot, otherwise uncompressed data could eat up all the
memory quickly. For my own large scale simulation of particles, one
snapshot generates as much as 14GB data for Tecplot, and preplot
shrinks them to 2GB! I will run Paraview in parallel processing mode,
but it is always optimal to compress ASCII data into binary before
loading them into Paraview.
Thanks,
Beichuan Yan

Hello.
Sorry, I made a mistake in my previous mail: I see in the Tecplot
reader help that it should be able to read unstructured:
The output of the reader is a vtkMultiBlockDataset, of which each
block is either a vtkStructuredGrid or a vtkUnstructuredGrid.
But I never succeeded in reading my own Tecplot unstructured grids
with triangle elements, so I can't help you for this type of file.
Also, I had some problems in reading some structured grids because
some Tecplot options in the ZONE card are not recognized by the
reader, and I had to suppress it. The Tecplot reader should still be
improved.
But if you try again Tecplot files with Structured or Unstructure
grids, don't forget the two header lines for title and variables.
Richard.
