I have looked and searched, this is the only difference I can find.
*[:blank:]* [:blank:] space and tab characters
*[:space:]* [:space:] whitespace characters
What are other whitespace characters are than space and tab?
On the Mac non-breaking space is xA0 and neither find it.
Search for /\%xA0 finds the Mac non-breaking space.
You have the right idea. Remember that a [...] character-class
can be prefixed by "\_" to include newlines, so you might do
something like
/the\_[[:space:]]\+brackets
(finds a match in my help on those POSIX-style character-classes)
whereas it won't find a match if you use [[:blank:]]
There are other Unicode whitespace characters (such as thin-space
and perhaps your non-breaking space, and other similar variants)
so [:blank:] is "JUST tabs and spaces" while [:space:] should
find any of the more generic whitespace.
