Description:
------------
Using an "Escape" \ in certain quotes, results in literal translation.

Tested on \r \n \t inside Single and Double quotes.

Single Quotes does not escape.
Double Quotes escapes.

I can not find documentation to explain this behaviour, or warnings on pages, related to places where one might try to use an escape.

Processed all Escapes inside any single ' and double " quotes.
or...
{Possible feature request}
SingleQuoteEscape=(all|none|quotes)
DoubleQuoteEscape=(all|none|quotes)

All = \r \n \t \\ \' {\"}
None = literal quoted text, must use CHR strings (Iso), No like-quotes allowed.
Quotes = if {'} then \' escape, if {"} then \" escape

Reproduce code:
---------------
<?
$MyString1 = '\tTest1\r\nABC1';
$MyString2 = "\tTest2\r\nABC2";

echo($MyString1.'<BR>'.$MyString2.);
?>

Expected result:
----------------
Expected Output:
	Test1
ABC1
	Test2
ABC2

Actual result:
--------------
Actual Output:

\tTest1\r\nABC1
	Test2
ABC2
