Functions
LLVM_READNONE bool	clang::isASCII (char c)
	Returns true if a byte is an ASCII character.
LLVM_READNONE bool	clang::isASCII (unsigned char c)
LLVM_READNONE bool	clang::isASCII (uint32_t c)
	Returns true if a codepoint is an ASCII character.
LLVM_READNONE bool	clang::isASCII (int64_t c)
LLVM_READONLY bool	clang::isAsciiIdentifierStart (unsigned char c, bool AllowDollar=false)
	Returns true if this is a valid first character of a C identifier, which is [a-zA-Z_].
LLVM_READONLY bool	clang::isAsciiIdentifierContinue (unsigned char c)
LLVM_READONLY bool	clang::isAsciiIdentifierContinue (unsigned char c, bool AllowDollar)
	Returns true if this is a body character of a C identifier, which is [a-zA-Z0-9_].
LLVM_READONLY bool	clang::isHorizontalWhitespace (unsigned char c)
	Returns true if this character is horizontal ASCII whitespace: ' ', '\t', '\f', '\v'.
LLVM_READONLY bool	clang::isVerticalWhitespace (unsigned char c)
	Returns true if this character is vertical ASCII whitespace: '\n', '\r'.
LLVM_READONLY bool	clang::isWhitespace (unsigned char c)
	Return true if this character is horizontal or vertical ASCII whitespace: ' ', '\t', '\f', '\v', '\n', '\r'.
LLVM_READONLY bool	clang::isDigit (unsigned char c)
	Return true if this character is an ASCII digit: [0-9].
LLVM_READONLY bool	clang::isLowercase (unsigned char c)
	Return true if this character is a lowercase ASCII letter: [a-z].
LLVM_READONLY bool	clang::isUppercase (unsigned char c)
	Return true if this character is an uppercase ASCII letter: [A-Z].

	Return true if this character is an ASCII hex digit: [0-9a-fA-F].
LLVM_READONLY bool	clang::isPunctuation (unsigned char c)
	Return true if this character is an ASCII punctuation character.
LLVM_READONLY bool	clang::isPrintable (unsigned char c)
	Return true if this character is an ASCII printable character; that is, a character that should take exactly one column to print in a fixed-width terminal.
LLVM_READONLY bool	clang::isPreprocessingNumberBody (unsigned char c)
	Return true if this is the body character of a C preprocessing number, which is [a-zA-Z0-9_.

	Return true if this is the body character of a C++ raw string delimiter.
template<EscapeChar Opt, class CharT >
LLVM_READONLY auto	clang::escapeCStyle (CharT Ch) -> StringRef
	Return C-style escaped string for special characters, or an empty string if there is no such mapping.
LLVM_READONLY char	clang::toLowercase (char c)
	Converts the given ASCII character to its lowercase equivalent.
LLVM_READONLY char	clang::toUppercase (char c)
	Converts the given ASCII character to its uppercase equivalent.
LLVM_READONLY bool	clang::isValidAsciiIdentifier (StringRef S, bool AllowDollar=false)
	Return true if this is a valid ASCII identifier.
