character(13) data type in PostgreSQL database scaffolded as char data type in .NET Core 2.0

[LuisMezas]

I'm using Npgsql.EntityFrameworkCore.PostgreSQL version 2.0.1
I have the next issue. pgAdmin 4 generates SQL as following:

rfc character(13) COLLATE pg_catalog."default" NOT NULL,
CONSTRAINT pk_empresas PRIMARY KEY (rfc)

The entire database is scaffolded into my .NET Core 2.0 project using the next command in Package Manager Console, which is done correctly.

Scaffold-DbContext "Host=localhost;Database=database;Username=pgadmin;Password=xxxx" Npgsql.EntityFrameworkCore.PostgreSQL -force

Until here, everything is fine, but when I go the scaffolded class/model of the table where I have the SQL generated by pgAdmin 4 as commented before.

I have the property scaffolded as following:
public char Rfc { get; set; }
And I can't really work with this, as this only holds a single UTF-16 character 😭
I need to explicitly work with a set of characters with a length of 13.

Is there something I can do at the moment?

Fixed for 2.0.2, bug doesn't exist in 2.1.
