In this category, the images of 6-dots Braille patterns are numbering dots 1 to 6 vertically (as shown in the table on the right). These characters are assigned in the Unicode and ISO/IEC 10646 standards at the begining of the "Braille Patterns" block (in the subrange U+2800..U+283F) and ordered so that the lowest 6 bits of their code point values are numbered in the same order as this traditional numbering of dots in standard Braille patterns.

However their names given in the images below indicate the letters (without distinction of case), digits, or symbols mapped on those patterns in the French Braille standard. There are differences across languages (and scripts) about how their letters (or sometimes digrams or trigrams) are assigned to each symbol. However there's a consensus for the basic alphabet of each script, so basic Latin letters are normally assigned to the same Braille patterns in all languages using the same Latin letters (those standard mappings are shown with yellow background in the table below); some basic Latin letters not used within a given language may be replaced by other letters, digrams or symbols. Many Braille patterns may play also different roles contextually, by mean of a few special prefix patterns (to allow distinctions of capitals vs. minuscules; or letters vs. digits, maths symbols, and abreviations).

In this category, the images of 8-dots Braille patterns are named by numbering dots 1 to 6 vertically only on the top 3 rows like in the 6-dots patterns, adding dots 7 and 8 horizontally on the 4th row (as shown in the table on the left). These characters are assigned in the Unicode and ISO/IEC 10646 standards in the "Braille Patterns" block (in the subrange U+2800..U+28FF) and ordered so that the lowest 8 bits of their code point values are numbered in the same order as this traditional numbering of dots in standard Braille patterns.

The 64 first symbols in this set are equivalent to the set 6-dot patterns for Braille readers and used the same way (but in this category the images are displaying the positions of the two unused dots at the bottom, so their relative image height will be larger).

The extra 192 symbols that are possible with the 8-dot patterns may be used for scripts (such as large syllabaries or ideographs) requiring a larger number of distinctions with a reduced total number of symbols for the same text, or may be used for technical notations in specific domains, or in private use sets of abreviations explained by authors of each collection of Braille documents. However they require an advanced training for death readers to improve their tactile skills, so they are avoided most of the time as they slow down the reading and may cause confusion. For this reason, languages normally written with large syllabaries or ideographs will be preferably translitterated into another wellknown but reduced alphabet (using translitteration standards already used for the same languages) before being converted into suites of Braille patterns.
