Maandishi kwa Octal

Badilisha maandishi kuwa uwakilishi wa octal kwa urahisi

Chombo cha kubadilisha fedha

0 characters

Enter text to convert to octal. Choose between UTF-8 (supports all characters) and ASCII (only 128 characters). Spaces between octal values can be added or removed.

Usimbaji wa maandishi

Herufi za maandishi zinawakilishwa na nambari kwenye kompyuta. Mifumo tofauti ya usimbuaji hutumia nambari tofauti kwa wahusika:

ASCII

The ASCII (American Standard Code for Information Interchange) encoding uses 7 bits to represent 128 characters, including English letters (both uppercase and lowercase), digits, and common punctuation symbols. Each ASCII character can be represented by a unique number between 0 and 127.

UTF-8

UTF-8 ni usimbaji wa herufi za urefu tofauti ambao unaweza kuwakilisha kila herufi katika kiwango cha Unicode. Inatumia ka 1 hadi 4 kwa kila mhusika. UTF-8 inaendana nyuma na ASCII, ikimaanisha kuwa herufi 128 za kwanza za UTF-8 zinafanana na ASCII.

Mchakato wa Ubadilishaji

Kubadilisha maandishi kuwa octal kunahusisha hatua zifuatazo:

  1. Determine the numerical value of each character using the chosen encoding (ASCII or UTF-8).
  2. Convert each numerical value to its octal (base-8) representation.
  3. Kwa hiari, tenganisha kila thamani ya octal na nafasi ya usomaji.

Mfano: Badilisha "Hi" hadi Octal

Step 1: Convert each character to its numerical value (ASCII):

H → 72

i → 105

Hatua ya 2: Badilisha kila thamani ya nambari kuwa octal:

72 → 110 (in octal)

105 → 151 (in octal)

Step 3: Combine the octal values (with spaces):

110 151

Vidokezo vya Matumizi

  • When using ASCII encoding, any character outside the 7-bit ASCII range (128-255) will be converted to a question mark (?).
  • Usimbaji wa UTF-8 unaauni herufi zote za Unicode, ikiwa ni pamoja na alama maalum, emoji na herufi kutoka lugha zisizo za Kiingereza.
  • Kila herufi ya UTF-8 inaweza kuwakilishwa na maadili mengi ya octal ikiwa inatumia zaidi ya baiti moja.
  • Maadili ya octal mara nyingi hutumiwa katika kompyuta kwa ruhusa za faili na katika mifumo mingine ya urithi.
