This is incorrect: "To include a hyphen in the brackets of a character set as a literal character, you cannot escape it as you can other special characters because ColdFusion always interprets a hyphen as a range indicator."

You CAN escape the hyphen in a character class.

This can be demonstrated with:

Were the hyphen acting as a range, there would be five items in the array but since it is literal there are only the three.

until the empty string before “o” is matched should be until the empty string after “o” is matched.

For (?m), reFind("(?m)^two", "one#chr(10)#two") should return 5 instead of 4 because chr(10) counts.

Escape Sequence \\x should be \xdd. (d can have a hex value from 0 to f.)

Example of \x

<cfoutput>#reFind("\x43", "Adobe ColdFusion 10")#</cfoutput> returns 7.

<cfoutput>#reFind("\x46", "Adobe ColdFusion 10")#</cfoutput> returns 11.
