Punctuation—being mostly unimportant to 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 smaller as to not get confused with it.
The proper-noun mark is used when something is a specific person, place, or thing. It is not used exactly like capitals in English since the word at the start of a sentence is not always marked with the proper-noun mark.
