Yes, almost always. They are obvious from the form of the verb. The only potential problem is 3rd person, but as normally you have some context, the subject will probably be obvious from the context.
it says that I have a typo but that diagonal t letter isn't on my keyboard! ugh
It's not a variant of T, it's a variant of L. Of course, using L will also be treated as a typo. You just need a Polish keyboard. Or SwiftKey, if you are on your phone.
