How can I improve PDF to SVG conversion for some SVG viewers?

Q: We have tested some files using pdftron
(pdftron.PDF.Convert.ToSvg()) and encountered a few files for which
text output isn't good.

Any ideas what we can do to improve the conversion?

A: You may want to use the following option:

--individual_char_placement Some viewers do not support the default
text
                              positioning correctly. This option
works around
                              this issue to place text correctly, but
produces
                              verbose output. This option will
override
                              --remove_char_placement.

which should fix the problem. The default option is:

--remove_char_placement Disable the output of character
positions. This
                              will produce slightly smaller output
files than
                              the default setting, but many viewers do
not
                              support the output correctly.
