This might be computer science related question.

I am manipulating Japanese data and in some Japanese words, there are English
words and Numbers are in.

ＳＹＳＫＥＮ, 松井ケ丘３, コメリＨ＆Ｇ, 篠路７－１ are the examples.

I see spacing between 'special characters', which are not Japanese/Kanji. I am
trying to find convert them to normal(I guess it does not look normal to
Japanese) English like "SYSKEN, 松井ケ丘3, コメリH&G, 篠路7-1" but I cannot start to
where.

What those fonts? or spacing rules are called in Japan or world wide?

Please guide me to solve my assginments :(
