*TODO Misc property proposal

1. Possible stability policy invariant

- Z = whitespace - [\u0009-\u000D \u0085]

2. Add to Default_Ignorable_Code_Point

U+FFFC ( ) OBJECT REPLACEMENT CHARACTER

3. Change Scripts from Common to Specific for the following Other_Symbols

U+0CF1 ( ೱ ) KANNADA SIGN JIHVAMULIYA

U+0CF2 ( ೲ ) KANNADA SIGN UPADHMANIYA

U+FDFD ( ﷽ ) ARABIC LIGATURE BISMILLAH AR-RAHMAN AR-RAHEEM

About 1000 symbols have specific scripts:

4. We are inconsistent regarding manufactured symbols

㉠ is Script=Hangul, Other_Symbol

㋐ is Script=Katakana, Other_Symbol

⒜ is Script=Common, Other_Symbol

㊏ is Script=Common, Other_Symbol

㈹ is Script=Common, Other_Symbol

ⓐ is Script=Common, Other_Symbol

U+32CD ( ㋍ ) SQUARE ERG is Script=Common, Other_Symbol

U+3300 ( ㌀ ) SQUARE APAATO is Script=Katakana, Other_Symbol

U+337F ( ㍿ ) SQUARE CORPORATION is Script=Common, Other_Symbol

µ is Script=Common, Lowercase_Letter

U+1D400 ( 𝐀 ) MATHEMATICAL BOLD CAPITAL A is Script Common, Uppercase_Letter

There is no principled reason why ㉠ or ㌀ should not have Script=Common, like the others. Either that or the others have the appropriate scripts.

About a 1000 letters have Common Script, typically where they are functionally symbols:

5. I was using the subblocks (from NamesList) to help organize, and found the following:

Singular plus Plural forms.

In many cases, we have a subblock that is a singular form of a plural name. I'd suggest we always use the plural form for noun or noun phrases, even if there is only a single character in the subblock. That is "XXX symbol" => "XXX symbols". Adjectival phrases ("Arabic") would be left alone.

This would affect the following (plus perhaps more: I only checked singular forms where there was a regular plural also).

Additional consonant => Additional consonants

Additional letter => Additional letters

Circle => Circles

Circled Hangul syllable => Circled Hangul syllables

Consonant => Consonants

Currency symbol => Currency symbols

Dependent vowel sign => Dependent vowel signs

Double diacritic => Double diacritics

Extended Arabic letter => Extended Arabic letters

Format character => Format characters

Gender symbol => Gender symbols

Keyboard symbol => Keyboard symbols

Latin letter => Latin letters

Letter => Letters

Letterlike symbol => Letterlike symbols

Medievalist addition => Medievalist additions

Miscellaneous addition => Miscellaneous additions

Miscellaneous arrow => Miscellaneous arrows

Miscellaneous mark => Miscellaneous marks

Miscellaneous mathematical operator => Miscellaneous mathematical operators

Miscellaneous mathematical symbol => Miscellaneous mathematical symbols

Miscellaneous symbol => Miscellaneous symbols

Modifier letter => Modifier letters

Operator => Operators

Relation => Relations

Rest => Rests

Sign => Signs

Space => Spaces

Special => Specials

Special character extension => Special character extensions

Squared Latin abbreviation => Squared Latin abbreviations

Subjoined consonant => Subjoined consonants

Syllable => Syllables

Symbol => Symbols

Tamil symbol => Tamil symbols

Variant letterform => Variant letterforms

Vertical line operator => Vertical line operators

Vowel => Vowels

There are a number of cases where the subblock equals the block.

Singletons: If it is a singleton (the only subblock in the block), add more of a gloss.

Non-Singletons: also change by narrowing the description, or changing to just "Miscellaneous", since it doesn't make sense to have block X contain subblock X and Y; that would imply both that Y's are X's and that Y's are not X's.
