There is some code in place in `wp-includes/class-wp-locale.php` to work around this: {{{#!php =' ) ) { // Replace space with a non-breaking space to avoid wrapping. $thousands_sep = str_replace( ' ', ' ', $thousands_sep ); } else { // PHP < 5.4.0 does not support multiple bytes in thousands separator. $thousands_sep = str_replace( array( ' ', ' ' ), ' ', $thousands_sep ); } }}} Since we don't know how translators translate `number_format_thousands_sep` and `number_format_decimal_point` i don't think this is working in all cases. In the French translation files there is currently a multibyte non-breaking space char. Above code will not replace the multibyte non-breaking space char to a regular space.
