It’s quite hard to read and write in Hebrew because there are some letters which have two different characters.
K could be written by ק or כ
S have ס and ש
T: ט and ת
ב may be B or V
פ: F or P
More complicated with vowels.
A: א or ע. Sometimes it’s written, sometimes isn’t.
E, I, Y: mostly י. But sometimes it could be א, sometimes not written.
O: mostly ו. Also not written sometimes.
U: completely the same with O on the letter.
