a "word" character is any letter or digit or the underscore character, that is, any character which can be part of a perl "word ". the definition of letters and digits is controlled by pcre's character tables, and may vary if locale-specific matching is taking place (see "locale support" above). for example, in the "fr" (french) locale, some char- acter codes greater than 128 are used for accented letters, and these are matched by \w.
so, while both \d + and \d+? are prepared to adjust the number of digits they match in order to make the rest of the pattern match, (? \d+) can only match an entire sequence of digits.
