Hello Alamar,
Sorry, your code doesn’t work for me…
Here is my code for French people:
var valid_chars='-/. +';
Because, a lot of people in European Francophone countries (France, Switzerland, Belgium) write phone numbers with dots or slash or spaces.
Dots in France:
01.55.55.55.55
Dots and slash in Belgium:
010/55.55.55
Spaces in Switzerland:
022 555 55 55
However, these characters “(” and “)” don’t work at all 
This is why I customized my language tag “error_validator_phone” to learn customers how to write their phone number:
[QUOTE][field] number is mandatory,
and must consist of at least 10 digits.
You can write your number like this:
5555555555
555 555.55.55
55 55 55 55 55
55.55.55.55.55
55/55/55/55/55
55-55-55-55-55
Optionally preceded by your country code,
eg for Switzerland:
+41 055 555 55 55
