uuid string generator accepts invalid uuids

[record.nctu.cis91@…]

I've tried stream operator and string generator to convert string into uuids.
But the string generator one accepts some incorrect uuid representation.
For example, with the following strings:

• "0000-0000-0000-0000-000000000000"
• "------------------------------------"

String generator accepts but produce strange content, but stream operator will refuse them.

Maybe it's better to throw exception in such case?
To tell user such string is not a correct uuid representation.

I think

char const* d = std::find(digits_begin, digits_end, c);
return values[d - digits_begin];

should be

char const* d = std::find(digits_begin, digits_end, c);
if (d == digits_end)
    throw_invalid();
return values[d - digits_begin];
