Braille signs and their combinations sometimes different symbols in the text and mathematics font again. The marking of the transitions between the two Fonts are therefore of great importance. Three different techniques are available:
The choice of technique is context dependent.
Expect in documents with a large mathematical share Reading with maths script. For identification of the exchange It therefore often suffices to pass from text to math yes, lines with mathematical content using the layout stand out from the rest of the text.
A very frequently used design option for identifying Drawing mathematics fonts are on and off syncopations. There are lines around a number of forms indented relative to the previous text environment. Of the Change back to the text font is made by the beginning of a new line in the text layout. Be for the mathematical Passage requires several lines, the following should be noted:
Further design forms are, for example, edge markers. (see example 1.1.1 B02) or table columns (see Examples 1.1.1 B03 and 1.1.1 B04).

The clearest transitions from text to Mathematics writing and back with indicator and cancellation sign marked.
The indicator sign is just ahead of the first one Character of mathematics font. Except at the beginning of the line usually preceded by a space. It stands however immediately behind an opening text clip or a another symbol, which is followed by text without a space could.
The cancellation sign is immediately after the last one Sign of math script passage. This is followed by an empty or punctuation.
The mathematical font introduced with the notice Passages are mandatory with the cancellation mark. conclude. They may only be used by short, with the double drawing technology delimited text passages interrupted become.
Punctuation marks belong at the end of a mathematical passage usually not to mathematical expression itself For the sake of clarity, after the discontinuation of written sign, where they do not precede the dot 6 need (see "3.7 punctuation marks").

Text writing within a math script passage can also marked with arrival and cancellation signs become. The indicator sign is immediately before the first text characters behind one at the border cause blanks. The cancellation symbol follows immediately bar to the last text character.
In a maths passage, the text insertion is normal. wise in the same degree of reduction (short, full or basic font) like the rest of transmitted text.
These signs and cancellations may also be within be used a math script passage, the in turn is delimited by arrival and termination signs. On the other hand, in a message marked with an recorded text insert no mathematical insertions be included.
Wherever there is a change between text and math- may be expected, very short insertions of the each other font with the double-sheet technology be marked.

As a rule, punctuation marks belong at the end of a mathematical passage is not a mathematical expression. they may nevertheless in front of the double source at the border sign - where necessary with dot 6 - be written (see "3.7 punctuation marks"). Follow a math expression directly on leading punctuation mark (quotation marks, opening Parenthesis), the double sign technique can not be applied.
For readers, it must always be clear whether they are watching the Read text or math font. For the choice of each Appropriate engineering, the following considerations apply principles:
Caution is required for umlaut characters and @ss, which in the Mathematics writing as other characters, especially as break- dash and closing bracket, can be read. Punctuation must be preceded by Dot 6 are provided.

@Line separator between two immediately adjacent characters

In the inkprint is usually any mathematical "Sentence" alone on a line. A hyphen for identification There is a mathematical line break in the Blackletter not.
In Braille, a mathematical "sentence" often takes more than just a line. Therefore, a character is needed to be aware of the continuation in the next line makes.
The placing of spaces in the braille mathematics font is not arbitrary. If a line break is necessary, then distinguish between two cases:
In two other cases, characters with@(point 4) held together as it were:
@ (Dot 4) in these functions is not available with dot 4 confused, the integral part of some symbols - to Example _@e (Euro) or _@0 (degree sign) - is or in front of a letter as accent sign.

The notes to the Braille script - both in a separate section as well as in parentheses - are in the degree of reduction as the rest of the text written. See examples 6.3 B01 and 14.3 B07.
