The
echo "invalid characters like Å, å, Ä, ä or"
is providing the input data with illegal characters that need removal. I need some test data and this is one way to demo a command. And the command I am showing is
tr -dc " a-zA-Z0-9,\n"
and that is what removes the garbage. The tr command, in this form, lists the valid characters, not the invalid ones. You may need to add stuff to the list. To replace invalid characters with a space use
I have switched to single quotes which may be better if you need certain special characters to be accepted. In your case you may want to just do
Read the tr man page for more info.
I am working on AIX. We ftp files to a database. The flat files are having thousands of records and each record is having some 50 to 60 characters(there are fields having certain character length). In addition to some valid ascii characters some invalid characters like Å, å, Ä, ä or pipes creep in which... (5 Replies)
This is a pretty straight-forward question. Within a program of mine, I have a string that's going to be used as a filename, but it might have some invalid characters in it that wouldn't be valid in a filename. If there are any invalid characters, I want to get rid of them and essentially squeeze... (4 Replies)

Hi All -
I'm building a script wherein it is design to remove characters that are not accepted on a non-unicode database. Examples are the following: ï,¿,½,Â,é, etc.
I can easily sed those characters one-by-one but I there's a problem when other unicode characters are found. Is there any way to... (1 Reply)

iconv
ICONV(1) Linux Programmer's Manual ICONV(1)NAME
iconv - character set conversion
SYNOPSIS
iconv [OPTION...] [-f encoding] [-t encoding] [inputfile ...]
iconv -l
DESCRIPTION
The iconv program converts text from one encoding to another encoding. More precisely, it converts from the encoding given for the -f
option to the encoding given for the -t option. Either of these encodings defaults to the encoding of the current locale. All the input-
files are read and converted in turn; if no inputfile is given, the standard input is used. The converted text is printed to standard out-
put.
The encodings permitted are system dependent. For the libiconv implementation, they are listed in the iconv_open(3) manual page.
Options controlling the input and output format:
-f encoding, --from-code=encoding
Specifies the encoding of the input.
-t encoding, --to-code=encoding
Specifies the encoding of the output.
Options controlling conversion problems:
-c When this option is given, characters that cannot be converted are silently discarded, instead of leading to a conversion error.
--unicode-subst=formatstring
When this option is given, Unicode characters that cannot be represented in the target encoding are replaced with a placeholder
string that is constructed from the given formatstring, applied to the Unicode code point. The formatstring must be a format string
in the same format as for the printf command or the printf() function, taking either no argument or exactly one unsigned integer
argument.
--byte-subst=formatstring
When this option is given, bytes in the input that are not valid in the source encoding are replaced with a placeholder string that
is constructed from the given formatstring, applied to the byte's value. The formatstring must be a format string in the same format
as for the printf command or the printf() function, taking either no argument or exactly one unsigned integer argument.
--widechar-subst=formatstring
When this option is given, wide characters in the input that are not valid in the source encoding are replaced with a placeholder
string that is constructed from the given formatstring, applied to the byte's value. The formatstring must be a format string in the
same format as for the printf command or the printf() function, taking either no argument or exactly one unsigned integer argument.
Options controlling error output:
-s, --silent
When this option is given, error messages about invalid or unconvertible characters are omitted, but the actual converted text is
unaffected.
The iconv -l or iconv --list command lists the names of the supported encodings, in a system dependent format. For the libiconv implementa-
tion, the names are printed in upper case, separated by whitespace, and alias names of an encoding are listed on the same line as the
encoding itself.
EXAMPLES
iconv -f ISO-8859-1 -t UTF-8
converts input from the old West-European encoding ISO-8859-1 to Unicode.
iconv -f KOI8-R --byte-subst="<0x%x>"
--unicode-subst="<U+%04X>"
converts input from the old Russian encoding KOI8-R to the locale encoding, substituting an angle bracket notation with hexadecimal
numbers for invalid bytes and for valid but unconvertible characters.
iconv --list
lists the supported encodings.
