This patch does:

  • Process *.??x files (non-English vim help files) not only *.txt files
  • Add charset tag <meta http-equiv="Content-Type" content="text/html; charset=$encoding">
    • $encoding = "latin1" by default
  • Detect !_TAG_FILE_ENCODING line in tags file
    • If vim2html.pl found this line, set the encoding value to $encoding

  • Process *.??x files (non-English vim help files) not only *.txt files
  • Add charset tag
    • $encoding = "latin1" by default
  • If the firstline of help file contains non-ASCII character, set "utf-8" to $encoding
