Suggested glyphs for complex scripts

Combining marks and signs that appear in text not in conjunction with a valid consonant base are considered invalid. Uniscribe displays these marks using the fallback rendering mechanism, on a dotted circle. For the fallback mechanism to work properly, an OTL font should contain a glyph for the dotted circle (U+25CC). In case this glyph is missing from the font, the invalid signs will be displayed on the missing glyph shape (white box).

To render a sign standalone (in apparent isolation from any base) one should apply it on a space. Uniscribe requires a ZWJ (zero width joiner U+200C) to be placed between the space and a mark for them to combine into a standalone sign. A ZWNJ (zero width non-joiner; U+200D) can be used between two letters to prevent them from forming a cursive connection.

Suggested glyphs for right-to-left scripts

In addition to the above glyphs for complex scripts, directional marks for right-to-left scripts should be included: LTR (left-to-right mark; U+200E), and RTL (right-to-left mark; U+200F).
