I like the tr solution.
But it needs \n to not fold the lines.
Retain the original number positions:
Code:
tr -c '[:digit:]\n' '[ *]' < file

Sqeeze the space to one:
Code:
tr -sc '[:digit:]\n' '[ *]' < file

BTW with sed these are
Code:
sed 's/[^[:digit:]]/ /g' file

Code:
sed 's/[^[:digit:]]\{1,\}/ /g' file

In \{n,m\} a missing m means "at least n".
In ERE this is {n,m} - but some awk do not have it implemented (and {1,} is the same as +).

locale::currency

Locale::Currency(3perl) 				 Perl Programmers Reference Guide				   Locale::Currency(3perl)

NAME

       Locale::Currency - standard codes for currency identification

SYNOPSIS

	   use Locale::Currency;

	   $curr = code2currency('usd');     # $curr gets 'US Dollar'
	   $code = currency2code('Euro');    # $code gets 'eur'

	   @codes   = all_currency_codes();
	   @names   = all_currency_names();

DESCRIPTION

       The "Locale::Currency" module provides access to standard codes used for identifying currencies and funds, such as those defined in ISO
       4217.

       Most of the routines take an optional additional argument which specifies the code set to use. If not specified, the default ISO 4217
       three-letter codes will be used.

SUPPORTED CODE SETS

       There are several different code sets you can use for identifying currencies. The ones currently supported are:

       alpha
	   This is a set of three-letter (uppercase) codes from ISO 4217 such as EUR for Euro.

	   Two of the codes specified by the standard (XTS which is reserved for testing purposes and XXX which is for transactions where no
	   currency is involved) are omitted.

	   This code set is identified with the symbol "LOCALE_CURR_ALPHA".

	   This is the default code set.

       num This is the set of three-digit numeric codes from ISO 4217.

	   This code set is identified with the symbol "LOCALE_CURR_NUMERIC".

ROUTINES

       code2currency ( CODE [,CODESET] )
       currency2code ( NAME [,CODESET] )
       currency_code2code ( CODE ,CODESET ,CODESET2 )
       all_currency_codes ( [CODESET] )
       all_currency_names ( [CODESET] )
       Locale::Currency::rename_currency  ( CODE ,NEW_NAME [,CODESET] )
       Locale::Currency::add_currency  ( CODE ,NAME [,CODESET] )
       Locale::Currency::delete_currency  ( CODE [,CODESET] )
       Locale::Currency::add_currency_alias  ( NAME ,NEW_NAME )
       Locale::Currency::delete_currency_alias	( NAME )
       Locale::Currency::rename_currency_code  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Currency::add_currency_code_alias  ( CODE ,NEW_CODE [,CODESET] )
       Locale::Currency::delete_currency_code_alias  ( CODE [,CODESET] )
	   These routines are all documented in the Locale::Codes man page.
