QIl reçoit 5 000 $ à la livraison. 5 000 $? ((2))

Thank you. This solution didn't quite work for me as it didn't end up replacing the text:


Code:
((1)) ((2))


I did however use this method of defining the variable with sed and it worked fine.

NAME
encoding - Manipulate encodings SYNOPSIS
encoding option ?arg arg ...? _________________________________________________________________ INTRODUCTION
Strings in Tcl are encoded using 16-bit Unicode characters. Different operating system interfaces or applications may generate strings in other encodings such as Shift-JIS. The encoding command helps to bridge the gap between Unicode and these other formats. DESCRIPTION
Performs one of several encoding related operations, depending on option. The legal options are: encoding convertfrom ?encoding? data Convert data to Unicode from the specified encoding. The characters in data are treated as binary data where the lower 8-bits of each character is taken as a single byte. The resulting sequence of bytes is treated as a string in the specified encoding. If encoding is not specified, the current system encoding is used. encoding convertto ?encoding? string Convert string from Unicode to the specified encoding. The result is a sequence of bytes that represents the converted string. Each byte is stored in the lower 8-bits of a Unicode character. If encoding is not specified, the current system encoding is used. encoding names Returns a list containing the names of all of the encodings that are currently available. encoding system ?encoding? Set the system encoding to encoding. If encoding is omitted then the command returns the current system encoding. The system encod- ing is used whenever Tcl passes strings to system calls. EXAMPLE
It is common practice to write script files using a text editor that produces output in the euc-jp encoding, which represents the ASCII characters as singe bytes and Japanese characters as two bytes. This makes it easy to embed literal strings that correspond to non-ASCII characters by simply typing the strings in place in the script. However, because the source command always reads files using the ISO8859-1 encoding, Tcl will treat each byte in the file as a separate character that maps to the 00 page in Unicode. The resulting Tcl strings will not contain the expected Japanese characters. Instead, they will contain a sequence of Latin-1 characters that correspond to the bytes of the original string. The encoding command can be used to convert this string to the expected Japanese Unicode characters. For example, set s [encoding convertfrom euc-jp "xA4xCF"] would return the Unicode string "u306F", which is the Hiragana letter HA. SEE ALSO
