How can I produce Unicode Character Charts (code block 2500-25FF) in Calc (want to do it 'programmatically')?

Hello, I wish to use the spreadsheet program, Calc, to create my own copies of codeblocks for reference. I find looking up characters laborious and an end to itself and I’m not always connected to the internet while I’m working, so local copies are a ‘good thing’!

It’s possible to enter Unicode characters one at a time with several series of keystrokes, but to produce a spreadsheet page, such as to include 2500-25FF would take days!! I’ve heard that charts such as this can be done in Excel, possibly Google Sheets. I would like to do so in Calc.

How is this possible? Any advice beyond how to enter single characters? Thanks!

Currently I’m using the following, but I think a solution would generalize to other versions and operating systems:
Program: Libre Office Calc: v. 24.2.6.2 (X86-64)
OS: Linux Mint 21.3 (6.8.04-8)
