Product Feed Specification - Restriction on id attributes
On https://support.google.com/merchants/answer/188494?vid=1-635761701146501002-2788016822 under Basic Product Information in 'id [id] - An identifier of the item' section there are following restricted type unicode characters mentioned :
- control characters (except carriage return 0x0D)
- function characters
- private area characters
- surrogate pairs
- non assigned code points (in particular any code point larger than 0x10FFFF)
Can you explain these with some examples and give range of these characters ?
Also if you can suggest some libraries(for java) which can help me in filtering these type of characters ?

a best-practice is to simply use plain us-ascii text,
with a mix of letters and numbers, -- in the ranges
of 30-39 and 61-7a (hex) or [0-9a-z] -- especially if
a spreadsheet is being used; e.g.
id must be unique per item across all data (feeds)
and should never change once assigned to an item.
