This is secure. You are correct. You have 76 characters. It's not completly random, but you have 76 characters or 19 words.

Can I use æ commands in my bitcoin password?

The only issue would be if this phrase is from a book or movie (potentially even one you are unaware of).  That is why systems like diceware exist to create a truly random sequence of words.

Although brute force capabilities have come a long way, passwords consisting of 10 digits (all keyboard symbols) are beyond the brute force (see below before you complain) capabilities of most entities and 12 digits would be beyond the capabilities of nation states in most situations (i.e. no nation is going to expend a year of super computing time at a cost of $500B in order to break your facebook password ).   If your a significant threat to a nation state and they would be willing to expend billions of dollars to attack you well you should probably push that out to 15 digits.  For those who prefer dicewords that would be 5, 6, and 8 dicewords respectively.

However that assumes the attacker is just doing a pure brute force attack of all possible passwords.  The reality is that beyond 9 digits it starts taking an increasingly incredible amount of time for each additional digits.  So password crackers are going to try a variety of methods which are often much faster (even on much longer passwords).

1) Check the hash against databases of known compromised passwords (you can find on various sites lists of 15M+ previously leaked and broken passwords).  If your passphrase is on that list your toast.  Even some hobbyist with a single CPU can break it in a matter of minutes.

2) Check the hash against phrases from movies, books, memes, pop culture (no doubt Satoshi's genesis block quote is insecure).

3) Check the hash against a dictionary (possibly foreign languages as well).

4) A modified version of #3 is to take the same dictionary and perform derivations (which is why Troub@dor1 is a lot weaker than it may initially seem).

So having a long passphrase is good but it isn't a guarantee that the password is strong (unless it is random).  To ensure it is strong it needs to not be breakable by the four methods above as well.  I noticed in your example you wrote "Tooast" not "Toast".  If that was intentionally then congratulations it ensured it probably isn't going to match any phrase search.

from what I read from someone's advice, one of the greatest way is to remember your password first then SHA256 it.
You may use any sort of encryption depends on your preference, as long as the encryption method is easy to acquire.
And use the encrypted hotword as raw password.

I use a similar approach. I write words intentionally wrong. A long time I used passwords like "ausdralia" or "intonesia". One different character should be enough. Just something like "d-t" or "b-p" or "g-k". And a two numbers which are conveniant to type.
-> short and no chance for a dictionary attack.

But way to short for a brain wallet. There you have to use more words. Take the places of your first trip in Thailand + your first car + one word written wrong-> done.

Here is a practical idea that would work for some people. It involves using a large random character list. Use your imagination to make it stronger than it is explained in the link: https://bt.irlbtc.com/view/435050.msg4779209#msg4779209.

The only thing that matters is how predictable each character is.

Truly random ASCII printable characters have about 6 bits of entropy each. You probably want between 64 and 128 bits of entropy (11-22 characters). That implies 100 character passwords are excessive.

I sometimes hash a file that changes over time, and use the resulting 32 hex digits (4 bits each) as a high-security password.

Well 42 bits of entropy is also awful.  Even if it wasn't on a password list, it could be brute forced by just about anyone and then once it is, it will be on a password list.  Really one should be look at a minimum of 80 bits of entropy and for high security applications more is better (128 bits would be optimal).

Still I do like the fact that the linked password meter checks against known weak/broken passwords.
