If a shape is followed by a space then no termination symbol is needed. If however the shape symbol is followed by punctuation, or unspaced from a following symbol, then the shape terminator must be used.

The description within transcriber-defined shapes should be a short series of initials or a single grade 1 word. They should not be used if the print symbol is already covered elsewhere in the code. The definitions of all shape symbols should be available to the reader in either a transcriber's note or on a special symbols page.

The physical enclosure indicator signals a combining of the item just prior (the outer symbol) with the item immediately following it (the inner symbol), where "item" is as defined in Section 11.4.1.

Refer to: Guidelines for Technical Material, Part 14.3, of Shape and Composite Symbols, for superposition, horizontal juxtaposition and vertical juxtaposition of print symbols.

When a print grouping symbol stretches across several lines of print, use the appropriate enlarged grouping symbol in braille. Repeat the grouping symbols directly under each other on each line. Use blank lines before and after such arrangements for clarity. 

The general UEB principles on the choice of single letter, word or passage mode apply; in particular, a capital terminator should not be used within a two-letter chemical element symbol. Using single capital indicators for chemical formulae provides a uniform appearance to the braille; nevertheless, there may be a clear advantage in using capital passage mode in some cases. Letters representing chemical elements should never be contracted.

Follow the provisions of Sections 4.2 and 4.3, Letters and Their Modifiers for the treatment of ligatured letters and the macron.

Use uncontracted braille for Old English, that is, English written before about 1100.

In Middle English (c. 1100 to c. 1450) the use of contractions is optional. When contractions are used, have regard for spelling variations.

Use contracted braille for Early Modern English (c. 1450 to c. 1650) having regard for spelling variations.
