You may have missed my follow up post, where I said I had not noticed you
were operating on a binary .doc file.
If you're not willing or able to use a full-blown doc parser, say by
controlling Word or LibreOffice, the other alternative is to do something
quick and dirty that might work most of the time. Open a doc file, or
multiple doc files, in a hex editor and *hopefully* you will be able to
see chunks of human-readable text where you can identify how en-dashes
and similar are stored.
I created a .doc file and opened it with UltraEdit in binary (Hex) mode.
What I see is that there are two characters, one for ndash and one for mdash,
each a single byte long. 0x96 and 0x97.
So I tried this: fStr = re.sub(b'\0x96',b'-',fStr)
that did nothing in my file. So I tried this: fStr =
re.sub(b'0x97',b'-',fStr)
which also did nothing.
So, for fun I also tried to just put these wildcards in my re.findall so I
added |Part \0x96|Part \0x97 to no avail.
Obviously 0x96 and 0x97 are NOT being interpreted in a re.findall or re.sub
as hex byte values of 96 and 97 hexadecimal using my current syntax.
So here's my question...if I want to replace all ndash or mdash values with
regular '-' symbols using re.sub, what is the proper syntax to do so?
Thanks!
0x96 is a hexadecimal literal for an int. Within a string you need \x96
(it's \x for 2 hex digits, \u for 4 hex digits, \U for 8 hex digits).
