Description
This class provides static methods that are UTF-8 capable variants of the same functions in Poco/String.h.
The various variants of icompare() provide case insensitive comparison for UTF-8 encoded strings.
toUpper(), toUpperInPlace(), toLower() and toLowerInPlace() provide Unicode-based character case transformation for UTF-8 encoded strings.
removeBOM() removes the UTF-8 Byte Order Mark sequence (0xEF, 0xBB, 0xBF) from the beginning of the given string, if it's there.

escape 
static std::string escape(
const std::string & s,
bool strictJSON = false
);
Escapes a string. Special characters like tab, backslash, ... are escaped. Unicode characters are escaped to \uxxxx. If strictJSON is true, \a and \v will be escaped to \\u0007 and \\u000B instead of \\a and \\v for strict JSON conformance.
escape
