∟Escape Sequences for Unicode Characters

This section describes escape sequences for Unicode characters in 'string' literals.

Escape sequences are also need to allow us entering Unicode characters using their code values.

Since Unicode values are divided into two groups, two escape sequence formats are supported:

If \ is followed by u...., where .... are 4 hexadecimal digits, the escape sequence represents the Unicode character defined by the 2-byte value of the 4 hexadecimal digits. For example, "\ud7a3" represents the character of 힣.
If \ is followed by v........, where ........ are 8 hexadecimal digits, the escape sequence represents the Unicode character defined by the 4-byte value of the 8 hexadecimal digits. For example, "\v0001F60B" represents the character of .

Both upper case and lower case of hexadecimal digits are supported.

Examples of "string" literals with escape sequences for Unicode characters:

write("\ud7a3 is a Korean Hangul character.");

write("\u000a is the same as \n.");

write("\v00020c96 is a Unicode supplementary character.");

write("\v0000000a is the same as \n.");

write("\v0000000A is the same as \n.");
