| 👍 ascii | 👎 utf-8 | |
|---|---|---|
Character encoding | 🔢 7-bit encoding Only 128 characters can be represented, including letters, numbers, and symbols. | 🔢 Variable-length encoding Can represent over 1 million characters, including characters from different languages and symbols.
|
File size | 📉 Smaller file sizes Since each character is represented by 7 bits, ASCII files are generally smaller than UTF-8 files. | 📈 Larger file sizes Since each character can be represented by 8 or more bits, UTF-8 files are generally larger than ASCII files.
|
Compatibility | 👍 Widely supported ASCII is supported by almost all computer systems and devices. | 👎 Less widely supported UTF-8 is not as widely supported as ASCII, especially on older systems and devices.
|
Speed | 🏎️ Faster processing ASCII is faster to process than UTF-8 because it uses a simpler encoding scheme. | ���� Slower processing UTF-8 is slower to process than ASCII because it uses a more complex encoding scheme.
|
Security | 🛡️ More secure ASCII is more secure than UTF-8 because it is less likely to be misinterpreted by malicious software. | 🔓 Less secure UTF-8 is less secure than ASCII because it is more likely to be misinterpreted by malicious software. |
