TText

A TText is a string of characters. Every character is defined as a Unicode code point. The string of characters is encoded in a byte array using a specific Encoding. Encodings can either use a fixed size for every character or use a variable size that depends on the character to be encoded. This means that in general operations on a text that reference characters at a certain index do not run in constant time. Instead, such operations have to scan the character string from the beginning up to the desired character index. Fortunately most operations on a text do not need to reference a character at an index directly, instead, often it suffices to iterate through the characters in a text using an explicit iterator or a for Character in Value loop.
