How can I input and display unicide characters? 
then I would like to add the characters to a special pallet.

Adding a library path...

I need to add a library path name to get an old style package .lib to run. Currently a have to manually add the path. How do I solve this?
Also should the package be convverted to .mla type?  What is the difference?

Edit;- I am using windows 10

Could anyone tell me what type of matrix normalisation this is and it it built into Maple? I found this in a paper and Google AI said this is the process of normailsation being used.

Type checking for a kind of set...

I am trying to add this to my type list in a package, but cannot get it to work.

TypeTools:-AddType(_L3DP, set(satisfies(s -> type(s, [algebraic $ 3])),'Vector[column](3, algebraic)'));

when I test with this I get an error.

 type({[7,8,9],<1,2,3>},:-_L3DP);
Error, testing against an invalid type

or this 

type({[7,8,9],<1,2,3>},set(satisfies(s -> type(s, [algebraic $ 3])),'Vector[column](3, algebraic)'));
Error, testing against an invalid type
