chm2pdf fails when filename contains special characters

[prasad]

Probably similar to
#500262 Errors if file name contains escaped special characters (space, parenthesis etc)

I have a chm file which has special characters in file name i.e. open and close bracket. These characters must be escaped when used with shell command. Otherwise, shell reports errors.

For example:
prasad@pjoshi:~/sources/chm2pdf-read-only$ chm2pdf --book "(1)_1.chm"
sh: 1: Syntax error: word unexpected (expecting ")")
sh: 1: Syntax error: word unexpected (expecting ")")
sh: 1: Syntax error: "(" unexpected
Something wrong happened when launching htmldoc.
exit value: 512
Check if output exists or if it is good.
Done.

chm2pdf runs shell utilities and commands like rm, htmldoc using os.system(). I suppose, os.system() start a shell and pass the command to it. Therefore, if file has special characters the command fails.

Thanks and Regards,
Prasad

  Handle CHM file names with special characters in name

  If a file has special characters in the file name, then it must be quoted
  correctly when the shell is involved.

  chm2pdf runs shell utilities and commands like rm, htmldoc using
  os.system(). I suppose, os.system() start a shell and pass the command to
  it. Therefore, if file has special characters chm2pdf fails.

  For example

  prasad@pjoshi:~/sources/chm2pdf-read-only$ chm2pdf --book "(1)_1.chm"

  The patch fixes the problem by properly quoting the file name string.
