Filesystem server for legacy, non-UTF-8 files. Auto-detects and converts 24 encodings (CP1251, CP1252, ISO-8859-x, KOI8-R/U, GBK/GB18030), keeps each file's original encoding on write, and manages BOM and line endings. Encoding-aware grep, partial reads with offset/limit for large files, and allowed-directory confinement. Single Go binary, no runtime dependencies.

Generate IDs, QR codes, and hashes, encode values, geolocate IPs, plus gated host diagnostics.
