Dealing with garbled text due to unknown encoding formats from multiple sources? This tool analyzes byte stream characteristics to identify the storage format of text files (such as UTF-8, GBK, and Shift-JIS). File encoding detection works by analyzing byte stream patterns to recognize text storage formats, outputting the corresponding encoding type for each file to help users resolve cross-platform text compatibility issues.
How do you determine if a file is UTF-8 encoded?
It is identified through a BOM (Byte Order Mark) or the continuous byte pattern of non-ASCII characters. For files without a BOM, the validity of multi-byte sequences must be verified.
Are there any limitations for batch detection?
Files larger than 10MB may affect response speed. Pure ASCII text might return multiple compatible encoding results (such as UTF-8 and Latin-1).
We recommend desensitizing sensitive files before uploading. Please be patient when processing large files. Results are for reference only; please double-check critical documents with a professional editor. Avoid submitting over 100 files consecutively.
For CSV files containing Chinese characters, prioritize verifying GBK/BIG5 encoding. For development logs, using UTF-8 without BOM is recommended. Example: .txt files generated by Windows systems are commonly encoded in GBK, while Linux system logs are mostly UTF-8.
