Top Forums UNIX for Advanced & Expert Users UTF-8,16,32 character lengths using awk Post 302961607 by Don Cragun on Tuesday 1st of December 2015 03:35:32 PM

The description of your problem is extremely confusing. UTF-8, UTF-16, and UTF-32 are completely different character sets and if you have a single file that contains characters from all three, determining which bytes in that file represent a <newline> character may be impossible unless you can clearly describe byte offsets in your file where there are shifts from one codeset to another and clearly describe how any program reading this file can determine what codeset is in use for any particular byte in that file.

If you are reading a file that is entirely encoded in UTF-8 (in which characters can be encoded with one to six bytes), you could tell your script that the UTF-8 input file was instead a file encoded in ISO 8859-1 (in which all characters are one byte) and count characters in lines in awk using the length() function since the <newline> character is encoded the same way in both codesets.

But, since you haven't described what the rest of your awk program is doing, we have no way to guess at whether or not this option might work for you and no way to guess if there might be other options.

NAME
cut - select out columns of a file SYNOPSIS
cut [ -b | -c] list [file...] cut -f list [-d delim] [ -s] OPTIONS
-b Cut specified bytes -c Select out specific characters -d Change the column delimiter to delim -f Select out specific fields that are separated by the -i Runs of delimiters count as one -s Suppres lines with no delimiter characters, when used EXAMPLES
cut -f 2 file # Extract field 2 cut -c 1-2,5 file # Extract character columns 1, 2, and 5 cut -c 1-5,7- file # Extract all columns except 6 DESCRIPTION
[file...]" delimiter character ( see delim)" with the -f option. Lines with no delimiters are passwd through untouched" Cut extracts one or more fields or columns from a file and writes them on standard output. If the -f flag is used, the fields are sepa- rated by a delimiter character, normally a tab, but can be changed using the -d flag. If the -c flag is used, specific columns can be specified. The list can be comma or BLANK separated. The -f and -c flags are mutually exclusive. Note: The POSIX1003.2 standard requires the option -b to cut out specific bytes in a file. It is intended for systems with multi byte characters (e.g. kanji), since MINIX uses only one byte characters, this option is equivalent to -c. For the same reason, the option -n has no effect and is not listed in this man- ual page. SEE ALSO
