String member functions assume list instead of char array like Adobe

Description

Lucee's has String.map() and String.each() as aliases for String.listMap() and String.listEach() – see this ticket
https://luceeserver.atlassian.net/browse/LDEV-388

However, this is causing compat issues with Adobe which treats a string as a char array when using the non-"list" version of the function. Also, Adobe has String.reduce() which Lucee does not support at all.

So in short, ONLY these methods should use list functionality:

  • String.listMap()

  • String.listEach()

  • String.listReduce()

And each of these should treat the string as a char array, looping over each character.

  • String.map()

  • String.each()

  • String.reduce()

Compare the behavior of each engine with the following snippet of code:

<ul> <cfscript> days = "1,3,5"; days.each( (i) => writeOutput( '<li>#i#</li>' ) ); </cfscript> </ul>

Now the string functions stringEach(), stringEvery(), stringFilter(), stringMap(), stringSome(), stringSort() and stringReduce() (as well as member functions) were added in lucee 6.0. I marked this ticket as deployed.

But those functions have incompatibility with ACF. Already I created a separate ticket for this issue ( https://luceeserver.atlassian.net/browse/LDEV-3772 )

I added a testcase to listFilter() and adjust some list functions testcases

I've checked this ticket and confirmed this issue happened on the lucee latest version 5.3.9.13-SNAPSHOT too. String member functions String.each(), String.every(), String.map(), String.some() treats the given string as a list instead of iterates over every character in the string. Also, lucee doesn't support the member functions String.filter(), String.sort().
