What is the code U0420?
U+0420 is the Cyrillic capital letter Er (Р), the Cyrillic counterpart of the Latin R sound. It visually resembles the Latin letter P in many fonts, but it is a distinct Unicode character used across languages that use the Cyrillic script.
Identity and basic facts
The following notes summarize the essential facts about this code point.
- Official Unicode name: Cyrillic Capital Letter Er
- Code point: U+0420 (hex); decimal value 1056
- Script and block: Cyrillic block (U+0400 to U+04FF)
- Glyph: Р (uppercase); lowercase form is р (U+0440)
- Common languages using this letter: Russian, Ukrainian, Bulgarian, Serbian, and many other languages that use Cyrillic
In summary, U+0420 identifies a specific Cyrillic letter, the uppercase Er, which plays a key role in many Slavic languages despite its visual similarity to Latin characters.
Encoding and rendering
To represent this code point in digital text, you can rely on standard Unicode encodings and numeric references. The following notes explain practical representations.
- Unicode notation: U+0420
- UTF-8 encoding: 0xD0 0xA0
- UTF-16 encoding: 0x0420
- HTML/XML numeric character references: Р or Р
- Programming escapes: in JavaScript or Java, use \u0420
- Common usage tip: ensure your text uses a Unicode-compatible font to render Cyrillic characters accurately
In summary, U+0420 can be encoded and rendered in multiple ways depending on the technology stack, with UTF-8 as the dominant web standard and hex/decimal references widely used in code and documents.
Typing, rendering, and practical notes
Because U+0420 is a Cyrillic character, you may need to switch to a Cyrillic keyboard layout or use a character picker when typing. Web pages and software typically render it correctly when UTF-8 encoding is used; mismatched encodings can cause garbled text or mojibake.
Common typing and rendering tips
Useful guidelines to ensure correct display and input include using UTF-8 everywhere, verifying fonts support Cyrillic, and using explicit numeric references when sharing text across systems with uncertain encoding.
Common confusions and practical tips
Several points help distinguish U+0420 from visually similar characters and avoid encoding pitfalls.
- The uppercase Cyrillic Er (Р) often looks like the Latin letter P, not R, which can cause visual confusion.
- U+0420 is not the same as the Latin capital letter R (U+0052); they are different characters with different meanings.
- Text containing Cyrillic characters can suffer mojibake if encoded or decoded with mismatched encodings (e.g., mixing UTF-8 with a legacy single-byte encoding).
- To minimize issues when exchanging text, prefer UTF-8 and include proper encoding declarations in web documents or data streams.
In summary, be mindful of the visual similarity to Latin letters, and ensure consistent encoding practices to preserve the correct Cyrillic text.
Summary
U+0420 is the Cyrillic Capital Letter Er, a distinct Unicode character used across Cyrillic-based languages. It represents the 'r' sound and is uppercase Р, with lowercase р (U+0440). It can be encoded in UTF-8 as 0xD0 0xA0, in UTF-16 as 0x0420, and referenced in HTML as Р or Р. Proper encoding and font support are essential to render it correctly on the web and in software.
