Errors-To: icon-group-errors
Status: RO
Does anyone know how regular expressions like [a-z] work when a
non-alphanumeric character is used? For example, which characters would
the following regular expression match?
[1-!]
What about this one?
[a-1]
And the reverse?
[1-a]
I'm sure all of this could be predicted if one had knowledge of the
ordering of ASCII, but I'm afraid I lack such knowledge. Any tips?
Thanks in advance.
Regards,
Stuart Robinson
