Converts texts from the auto-detected encoding to UTF-8 or a specified encoding.
This is similar to the iconv
command but differences are following.
- Detects encoding if the source encoding is not specified.
- Replaces malformed byte sequences with the REPLACEMENT CHARACTER or the corresponding numeric character reference, which depends on the destination charset (i.e. Unicode or not).
- Can recursively convert files in directories and output converted files to the specified directory preserving the directory hierarchy.
Since this library depends on encoding_rs
, available encodings are the ones defined in the Encoding Standard.
Note: UTF-16 files are needed to have a BOM to be detected as the encoding.
This is because chardetng
, on which this library depends, does not support UTF-16 and this library only added BOM sniffing to detect UTF-16.
cargo install aconv
Converts texts from the auto-detected encoding to UTF-8 or a specified encoding.
If byte sequences that is malformed as Unicode are found,
they are replaced with the REPLACEMENT CHARACTER(U+FFFD).
If the destination encoding is not Unicode and unmappable characters are found, they are
replaced with the corresponding numeric character references.
If the encoding detection is considered it failed, the input texts are output as-is,
meaning no conversion takes place, and an error message is emitted.
USAGE:
aconv [FLAGS] [OPTIONS] [FILE]...
FLAGS:
-h, --help Prints help information
-l, --list Prints supported encodings
-q, --quiet Suppresses error messages when encoding detection failed
-s, --show Only shows auto-detected encodings without decoded texts
-V, --version Prints version information
OPTIONS:
-o, --output <DIRECTORY> Output directory. If input arguments contain directories, the directory
hierarchies are preserved under DIRECTORY
-t, --to-code <ENCODING> The encoding of the output [default: UTF-8]
-A, --non_ascii_to_guess <NUMBER> The number of non-ASCII characters to guess the encoding. Around 100
characters are enough for most cases, but if the guess is not accurate,
increasing the value might help [default: 100]
-T, --non-text-threshold <PERCENTAGE> The threshold (0-100) of non-text character occurrence. Above this
threshold in decoded UTF-8 texts, the encoding detection is treated as it
failed. In that case the input texts are output as-is with an error message
emitted [default: 0]
