Phonemic material within a text is normally enclosed in solidi (forward slashes) in print. Use the opening IPA slash and the closing IPA slash.

When IPA Braille and one other non-UEB braille code are used in a text, then non-UEB indicators can be used without identifiers for the other non-UEB braille code.

When print does not use square brackets or solidi (forward slashes) to identify IPA material, and when the nature and extent of the material cannot be determined by context or format, then use the general opening IPA indicator and the general IPA terminator to enclose the IPA material.

To temporarily switch from IPA Braille to UEB, use the general IPA terminator and return to IPA Braille with the general opening IPA indicator.

Transcribe music according to the provisions of New International Manual of Braille Music Notation. Follow its provisions to determine when indicators are needed to switch between UEB and music braille.

To switch from UEB to music braille when an indicator is necessary, leave a space and place the opening music indicator immediately before the musical notation.

Follow the provisions of New International Manual of Braille Music Notation for returning to UEB from music braille.

When technical material is transcribed according to the provisions of The Nemeth Braille Code for Mathematics and Science Notation within UEB text, the following sections provide for switching between UEB and Nemeth Code.

Place the opening Nemeth Code indicator followed by space before the sequence to which it applies. Its effect is terminated by the Nemeth Code terminator preceded by space. 

Note: The spaces required with the indicator and terminator do not represent spaces in print.

When the Nemeth Code text is displayed on one or more lines separate from the UEB text, the opening Nemeth Code indicator and the Nemeth Code terminator may each be placed on a line by itself.
