Re: [alreq] Characters that are not used for Arabic/Persian (#277)

> The following tables list Unicode characters used for Arabic script.

What does this mean? Is it that these characters are available in Arabic keyboard layouts? Or that they're commonly used in online Arabic texts? and what sort of Arabic (Classical Arabic or Modern Standard Arabic)? This needs to be clarified.

* For example `U+0671 ARABIC LETTER ALEF WASLA` is used in Quran and Classical Arabic manuscripts, but not in MSA. Same goes for U+0653-U+670

Until such standard for Arabic is published, it is safe to dismiss `U+0020 SPACE` and `U+002A ASTERISK` as not being used. It is easy to verify that those characters are used in numerous Arabic books and online webpages. 

As for why Persian doesn't use `U+0022 QUOTATION MARK`, this is because quotation marks differ depending on the locale. See this [Wikipedia table](https://en.wikipedia.org/wiki/Quotation_mark#Summary_table). They also need not to be used in Arabic text, but since they're in the default layout, they are used as semantic quotes rather than typographical quotes (e.g: see https://github.com/jgm/pandoc/issues/10013).
