أداة: Ascii converter
ما الذي يقدمه هذا القسم
Classic ASCII assigns meanings to the integers 0–127—control characters, digits, Latin letters, punctuation. Modern web pages routinely use Unicode beyond that range (emoji, accents), which means some characters do not have a classic ASCII code at all; tools may show decimal Unicode scalar values, substitute placeholders, or refuse out-of-range input. Read the on-page behavior before you grade homework.
متى تستخدمها
Use it when comparing serial protocols that still speak 7-bit ASCII, when debugging why a barcode scanner emits control codes, or when teaching number bases alongside letters. For full UTF-8 byte visibility, prefer أداة: Hex converter or أداة: Binary converter; for readable spellings of amounts, try Number إلى words converter.
مثال عملي
The digit 5 maps to decimal 53 in ASCII—different from the integer value five people imagine when typing math. Seeing that distinction prevents off-by-one bugs in simple parsing exercises.
أسئلة شائعة
Is this tool "Unicode aware"?
ASCII is a subset of Unicode. Characters outside U+007F need broader tables than vintage ASCII charts.
What about "extended ASCII"?
Vendor-specific pages like Windows-1252 overlap names but differ by locale—never assume byte meanings without specifying the encoding.
Why control characters look empty?
Codes under 32 are non-printing; editors may hide them unless escaped.
