A string is a sequence of characters. Strings can be made up of multiple concatenated substrings. There is no general limit on the length of a string, although Keyman does impose limits on strings in various situations.

The following string formats are available:

Quoted stringsa list of characters, enclosed either by " or ' quote characters. Can only use characters in the range decimal 32 - 255. To use quotes in the string, enclose with the other quote type.
store (vowels) "aeiou"
+ '"' > 'quote'
Decimal character codesa single character, in decimal format. Range d32 - d1114111.
+ d32 > 'space'
Hexadecimal character codesa single character in hexadecimal format. Range x20 - x10FFFF.
+ x20 > 'space'
Octal character codesa single character in octal format. Not recommended - only included for historical reasons. Range 40 - 4177777.
+ 40 > 'space'
Unicode character codesa single character in U+xxxxxx format. Recommended for Unicode. Range U+0020 - U+10FFFF.
+ U+0020 > 'space'

Strings are concatenated by listing them together, separated by spaces. For example, the following two lines are equivalent:

U+0041 U+0042 d67 d68 "abc"
