Use the non-UEB passage indicators when there are three or more symbols-sequences in the non-UEB braille code. The effect of a nonUEB passage indicator continues until the closing non-UEB passage indicator.

When more than one non-UEB braille code is used in a particular text and it is not obvious which one is intended, modify the opening nonUEB passage indicator by augmenting it with an identifier. Before the dot 3, insert a short, mnemonic sequence of letters (no contractions) which is unique within the text. The transcriber determines the abbreviations used. Refer to ISO Standard 639-3 (on the website of SIL International, http://www-01.sil.org/ISO639-3/codes.asp) for a list of two- and three-letter designations for languages.

Identifiers are not used with the non-UEB word indicator. If an identifier is required, use the opening and closing non-UEB passage indicators, even if it is only for one symbols-sequence.

When more than one non-UEB braille code is used in a text, use a non-UEB indicator without an identifier only when its meaning is obvious or when it refers to the same code as the next previous nonUEB passage within the paragraph.

Close any non-UEB passage before opening another non-UEB passage. In other words, return to UEB first even if another non-UEB passage will start immediately.

When the non-UEB text is displayed on one or more lines separate from the UEB text, the opening and closing non-UEB passage indicators may each be placed on a line by itself.

Except in the previous instance, place non-UEB indicators at the exact point of change from UEB to non-UEB and back, unspaced from the symbols-sequence(s) which they precede or enclose. That is, do not insert spaces which are not already present in the text.

When a non-UEB code provides a symbol for switching out of that code, use that symbol in preference to the non-UEB word terminator or the closing non-UEB passage indicator.

Transcribe phonetic and phonemic material according to the provisions of IPA Braille: An Updated Tactile Representation of the International Phonetic Alphabet. The following sections provide for switching between UEB and IPA Braille.

Generally phonetic material within a text is identified in print by being enclosed in square brackets. Use the opening IPA bracket and closing IPA bracket. The effect of the opening IPA bracket is terminated only by the closing IPA bracket and not by a space.
