The GOLD Builder has a collection of useful pre-defined sets at your disposal. These include the sets that are often used for defining terminals as well as characters not accessible via the keyboard.
| Name | Codepoint | Description |
|---|---|---|
| {HT} | &09 | Horizontal Tab character. |
| {LF} | &10 | Line Feed character. |
| {VT} | &11 | Vertical Tab character. This character is rarely used. |
| {FF} | &12 | Form Feed character. This character is also known as "New Page". |
| {CR} | &13 | Carriage Return character {#13}. |
| {Space} | &20 | Space character. Technically, this set is not needed since a "space" can be expressed by using single quotes: ' '. The set was added to allow the developer to more explicitly indicate the character and add readability. |
| {NBSP} | &A0 | No-Break Space character. The No-Break Space character is used to represent a space where a line break is not allowed. It is often used in source code for indentation. |
| {LS} | &2028 | Unicode Line Separator |
| {PS} | &2029 | Unicode Paragraph Separator |
Please see the Pre-Defined Character Set Chart for pictures of these characters.
| Name | Codepoints | Description |
|---|---|---|
| {Number} | &30 .. &39 | 0123456789 |
| {Digit} | &30 .. &39 | 0123456789 This set is maintained to support older grammars. The term "digit" is technically inaccurate and this set will eventually be removed, but not for a long time. Please use the {Number} set. |
| {Letter} | &41 .. &5A, &61 .. &7A | abcdefghijklmnopqrstuvwxyz ABCDEFGHIJKLMNOPQRSTUVWXYZ |
| {AlphaNumeric} | &30 .. &39, &41 .. &5A, &61 .. &7A | This set includes all the characters in {Letter} and {Number} |
| {Printable} | &20 .. &7E, &A0 | This set includes all standard characters that can be printed onscreen. This includes the characters from #32 to #127 and #160 (No-Break Space). The No-Break Space character was included since it is often used in source code. |
| {Letter Extended} | &C0 .. &D6, &D8 .. &F6, &F8 .. &FF | This set includes all the letters which are part of the extended characters in the first 256 characters (ANSI). |
| {Printable Extended} | &A1 .. &FF | This set includes all the printable characters above #127. Although rarely used in programming languages, they could be used, for instance, as valid characters in a string literal. |
| {Whitespace} | &09 .. &0D, %20, &A0 | This set includes all characters that are normally considered whitespace and ignored by the parser. The set consists of the Space, Horizontal Tab, Line Feed, Vertical Tab, Form Feed, Carriage Return and No-Break Space. |
| Name | Codepoints |
| {All Latin} | &41 .. &5A, &61 .. &7A, &AA, &B5, &BA, &C0 .. &D6, &D8 .. &F6, &F8 .. &024F, &1E00 .. &1EFF, &2C60 .. &2C7F, &A720 .. &A7FF |
| {All Letters} | This is too large to display here. |
| {All Printable} | &20 .. &7F, &A0 .. &200A, &2010 .. &2027, &202F .. &205F, &2065 .. &2069, &2070 .. &D7FF, &E000 .. &FEFE, &FF00 .. &FFEF |
| {All Space} | &20, &A0, &1680, &180E, &2000 .. &200A, &202F, &205F, &3000 |

| {All Whitespace} | &09 .. &0D, &20, &85, &A0, &1680, &180E, &2000 .. &200A, &2028, &2029, &202F, &205F, &3000 |
Unicode is divided into different distinct sections for many of the world's languages. The GOLD Meta-Language contains a number of predefined sets based on the Unicode standard.
