2.6.2.3 Word indicator ¶

Many languages have special indicators for emphasized words. The scope of a word indicator is normally until the next unemphasizable character, however this can be changed with the emphmodechars opcode (see noemphchars and emphmodechars).

Word emphasis can also be canceled with an explicit closing indicator. Usually a word indicator is put at the the beginning of the word, but it may also be used for cases where the emphasis starts in the middle of the word.

begemphword <emphasis class> <dot pattern>

Braille dot pattern to indicate the beginning of an emphasized word or the beginning of emphasized characters within a word.

begemphword underline 456-36

endemphword <emphasis class> <dot pattern>

Word emphasis ends implicitly when the word ends. When an indication is required to close word emphasis, i.e. when emphasis ends in the middle of a word, then this opcode defines the braille dot pattern that is used.

endemphword transnote 6-3

When emphasis ends in the middle of a word and there is no endemphword definition, a letter indicator must be defined (see Letter indicator).

emphmodechars <emphasis class> characters

Normally, only spaces and unemphasizable characters (see space and noemphchars) will cancel the begemphword indicator (see begemphword). However this can be overruled with the emphmodechars opcode. If emphmodechars is specified, any character that is not in the specified list and is not a letter (see uppercase, lowercase or letter) will cancel the begemphword indicator. Conversely, letters and characters that are in the list will not cancel the word indicator.

Example:

emphmodechars underline -
