Replace UTF-8 with ASCII

We try to restrict non-ASCII to names.

Python does not accept U+2013 EN DASH as indicating a command-line
argument; U+2D HYPHEN-MINUS is required.

Replace U+201C LEFT DOUBLE QUOTATION MARK and U+201D RIGHT
DOUBLE QUOTATION MARK with ordinary ASCII quotes.

-      python doxy.py –i  doxy_xml_dir –o rst_dir –t func
+      python doxy.py -i  doxy_xml_dir -o rst_dir -t func
       This will result in the storing of the API function documentation files in rst format in the rst_dir. The file names are constructed based on the function name. For example, the file for krb5_build_principal() will be krb5_build_principal.rst
 
       Run:
-      python doxy.py –i  doxy_xml_dir –o rst_dir –t typedef
+      python doxy.py -i  doxy_xml_dir -o rst_dir -t typedef
       It is similar to the API function conversion, but for data types. The result will be stored under rst_dir/types directory
