[Character design standards] Improve description of U+0192

[moyogo]

The Charater design standards - Monetary characters for Latin 1 page has the following description for U+0192 LATIN SMALL LETTER F WITH HOOK:

• Florin currency symbol (Dutch) Unicode: U+0192

  Design : This character's design is commonly based on the italic lowercase f design of the typeface.

  Alignment : Aligns with the lowercase ascender height and lowercase descender and it is dependent on the design of the typeface.

  Advance width : Advance width should be the same as the figure space width.

  Spacing : Spaces between figure zeros.

This should be improved to reflect the fact that U+0192 is used in Ewe language, Waci Gbe language, Lelemi language and Avatime language as a letter with its uppercase U+0191 LATIN CAPITAL LETTER F WITH HOOK where it needs to be upright in upright styles and italic in italic styles, and it's advance width should not be the same as the figure space width.

I’d go further and deprecate this character from the monetary symbols set altogether. Priority should be given to the orthographic form of the character, as its Unicode name suggests. It was a bad encoding unification, and one that would still benefit from being disunified, e.g. by adding FLORIN as a character of historical interest.
