I see that letter every now and then and I tought it was some kind of "L". Is it similar in Paweł as well?

Also found this page about it:

Yes, exactly - the same letter is used in name PAWEŁ (Polish male name, corresponds to English Paul). Probably for most foreigners pronunciation of "Ł" is completely different than "L" (and probably, objectively speaking, they ARE completely different), but for me the way Ł sounds is somehow similar to L... probably it is all because of their similar shapes in writing

Here are some of our funky letters and digraphs (compounds of two letters - they do not form any "separate" symbols when written together - they are still two separate letters - but when pronounced, they make one voice -> for example, I think that there is no difference in pronounciation between "CH" and "H" -> which sound simply like Turkish H; or "RZ" and "Ż", which I think sound similarly to Turkish "J" - probably not everyone would agree with me, but for me there is no difference at all )
