These unique numbers are called as code points in the unicode terminology. An exabyte is a large unit of computer data storage, two to the sixtieth power bytes. Wikipedia provides an illustrated explanation of how languages map into the BMP, among lots of other useful information.

Furthermore, various operations on the characters like uppercasing, lowercasing, and collating are defined. Unicode defines characters like LATIN CAPITAL LETTER A or GREEK SMALL LETTER ALPHA and unique numbers for the characters, in this case 0x0041 and 0x03B1, respectively. A code point is essentially the position of the character within the set of all possible Unicode characters, and thus in Perl, the term ordinal is often used interchangeably with it. A private grapheme may be assigned any code point value within the ranges U+E000 to U+F8FF, U+F0000 to U+FFFFF, and U+ to U+10FFFD. These code points are left undefined by the Unicode standards.
This is convenient if your keyboard lacks some desired accents and other diacritics. In this chapter we will tackle matters related to input encoding, typesetting diacritics and special characters. This chapter assumes you are using the latex or pdflatex engines and need to concern yourself with TeX’s various encodings. Lualatex and xelatex, on the other hand, accept Unicode input and can usually typeset documents using the correct glyphs without further user intervention. See the Fonts chapter’s discussion of encoding for additional information.
In order for computer systems to process text, the characters and other graphic symbols used in written languages must be converted to numbers that the computer can read. If your data comprises characters on the multilingual plane beyond those represented in ASCII, UTF-16 is a good choice. While UTF-8 is a varying-length encoding , UTF-16 is a fixed-length encoding – as long as you stick to the multilingual plane, every character occupies exactly two bytes. Consequently, the average number of bytes per character needed to represent text strings in UTF-16 ranges between two and four, inclusive.

If this inspired you to expand your language horizons, check out the best language learning apps that really work. See TechLanguage’s page on the international keyboard for more info on this. The Character Map contains more characters than you’d think at first glance. Check the Advanced view box to enable more options at the bottom. Select the Group by dropdown and you’ll find Chinese characters by Pinyin, Japanese Kanji by Hiragana, Korean characters, and more. The page contains hundreds of symbols ranging from currency to musical notes, units, arrows, math, and much more.

When you install a new language in Windows, it automatically enables the language bar. This is really useful for quickly switching between languages in Windows. You’re probably not going to be typing in one language for every application, so the language bar makes it easy to switch. You can also click on the Preview button to see how the characters for your language are mapped to the keyboard you are using.
