This note demonstrates how Python encodes and decodes Unicode strings using utf-8 and GBK, and how the chr() and ord() functions convert between characters and their ASCII codes, with concrete code examples and output illustrations.
This article answers a fan’s question by clarifying the distinction between Python’s encode() function and the encoding parameter, explaining how encode() defaults to UTF‑8, how explicit encoding strings work, and when each is used in string handling and web crawling.
This article explains the differences between Python 2 and Python 3 string encoding, demonstrates practical examples on Windows and Linux, and shows why Python 3’s default Unicode handling eliminates many common encoding errors.
This article explains why string encoding errors occur in Python, outlines the evolution from ASCII to GB2312 and Unicode, describes the variable‑length UTF‑8 format, and shows how to correctly convert between Unicode and UTF‑8 when reading or writing files.
This article investigates an Android JNI native crash caused by misusing NewString(), examines why a custom UTF‑8‑to‑UTF‑16 conversion was used instead of NewStringUTF(), compares Dalvik and ART string encodings, reveals a Dalvik UTF‑8 conversion bug fixed in ART, and advises developers on encoding nuances across Android versions.
