Legacy datasets often contain mixed or unknown character encodings, causing garbled text, unexpected symbols, or errors in data processing. These encoding issues arise due to differences in character sets, improper file conversions, or incompatibility with modern applications. In this tech concept, we will explore how to detect, fix, and standardise encoding issues in legacy text files using PHP. We’ll…
Managing encoded data in files is a frequent challenge, especially when dealing with XML, JSON, or other structured file types. URL-encoded characters like %20 (for spaces) or %3F (for question marks) can make data unreadable and difficult to process. Python provides a seamless way to handle these issues by decoding URL-encoded characters and replacing specific text efficiently. Two decades…
