This has come up many times before, but I'll ask once again in case
something has changed or someone new sees this.
Does anyone have a routine that will take a filespec to a text file and
return the guessed encoding of the text file?
First, please don't respond with your should know the encoding or the
users should know the encoding of their files. Not possible in the
widely uncontrolled real world.
I do already have a routine to guess file encodings. It was written by
someone else. There are instances where it should work and does not. I
fear there may be errors in the algorithm and I do not have the original
algorithm to check it against. Hence, I am looking for an alternative
that is either free to use or to be licensed for a modest fee.
My current routine attempts to return the encoding as a string that can
be directly passed to textDecode(binaryData,encoding)
"ASCII"
"UTF-16"
"UTF-16BE"
"UTF-16LE"
"UTF-32"
"UTF-32BE"
"UTF-32LE"
"UTF-8"
"CP1252" *
"MacRoman" *
* for these last 2, if the file is MacRoman on a Windows system, you
actually have to textDecode(macToISO(data),"CP1252") and if you have
CP1252 on the Mac, you need to do textDecode(isoToMac(data),"MacRoman").
There is an enhancement request to support MacRoman decoding under
WIndows and vice versa at

yourself to show interest.
