* Backslash sequences like \n, \r and \\ have already been converted to LF, CR and backslash
* Backslash sequences like \n, \r, and \\ have already been converted to LF, CR and backslash
* characters, by virtue of the eval() function that all our component parameter strings pass through;
* eval() treats strings like "source code", so any backslash sequence that JavaScript supports is
* automatically converted.
*
* The complete list of supported backslash sequences:
* The complete list of backslash sequences supported by JavaScript:
*
* \0 \' \" \\ \n \r \v \t \b \f \uXXXX \xXX
* ^J ^M ^K ^I ^H ^L
*
* We also want to support some additional sequences, like backslash-e for ESC. Only one problem: for
* any unrecognized backslash sequence, eval() simply removes the backslash. So we have to double-backslash
* it, which eval() will replace with a single backslash.
*
* So, additional supported backslash sequences include:
*
* \\e (ESC)
*
* Note that I've judiciously avoided using terms "escape notation" or "escape sequence" to talk about
* these sequences, because ESC is one of the additional characters I want to support, and using the word
* "escape" in both contexts is WAY too confusing.
* To support any other non-printable 8-bit character, such as ESC, you should use \xXX, where XX
* is the ASCII code in hex. For ESC, that would \x1B.
