Punctuation—being mostly unimportant in deriving the meaning of a section of writing—can be omitted. However if needed the following marks can be used.
Marks with the "x" shape in them can be written with the lines of the "x" joined together. It should look similar to the F-L pair but noticably smaller as to not cause confusion.
The proper-noun mark is used when something is a specific person, place, or thing. It is not use exactly like capitals in English since the word at the start of a sentence is not always marked with the proper-noun mark.
