  1. UTF-8
    Best overall Majosta

    UTF-8

    5/5 $18.99

    Variable-length encoding that is backward-compatible with ASCII and widely supported across platforms.

    • ASCII-compatible
    • Efficient for English text
    • Wide support
    • Variable length can slow random access
  2. Best for legacy systems

    UTF-16LE

    4.8/5

    16-bit encoding with little-endian byte order, commonly used in Windows APIs and Java.

    • Consistent 16-bit width
    • Native to many systems
    • Supports all Unicode
    • Requires byte-order mark for portability
  3. Best for network protocols

    UTF-16BE

    4.8/5

    16-bit encoding with big-endian byte order, favored in network protocols and older Apple systems.

    • Endian-neutral with BOM
    • Consistent 16-bit width
    • Supports all Unicode
    • Requires byte-order mark for portability
  4. Best for fast random access

    UTF-32LE

    4.5/5

    32-bit fixed-length encoding that allows constant-time indexing but uses more storage.

    • Fixed-width indexing
    • Fast random access
    • Simple mapping
    • Large storage footprint
  5. Best for network protocols

    UTF-32BE

    4.5/5

    32-bit big-endian fixed-length encoding, rarely used but provides uniform byte order for transport.

    • Fixed-width indexing
    • Endian-neutral with BOM
    • Simple mapping
    • Large storage footprint
  6. Best for email encoding

    UTF-7

    3.0/5

    Base64-like encoding designed to transmit Unicode over 7-bit channels like older email systems.

    • 7-bit safe
    • Supports all Unicode
    • Designed for legacy media
    • Complex and error-prone
  7. UTF-1
    Historical interest YANMAR

    UTF-1

    2.0/5 $43.95

    Early variable-length encoding that has been deprecated in favor of UTF-8.

    • Historical significance
    • Early Unicode support
    • Unsupported today
    • Unstable mapping

Buying advice

When choosing an encoding, consider compatibility with existing systems, data size constraints, and language support. UTF-8 is generally the safest choice for web and modern applications, offering backward compatibility with ASCII, efficient storage for English text, and universal support across platforms.
