uconv 命令

常用示例

说明

uconv converts text between character encodings using the ICU (International Components for Unicode) library. It supports over 200 encodings and more than 1000 aliases, making it suitable for complex internationalization tasks. Beyond simple transcoding, uconv provides transliteration capabilities to convert text between scripts (e.g., Cyrillic to Latin) without translation. Multiple transliterators can be chained with semicolons. Error callbacks control handling of characters that cannot be mapped. Callbacks can be set independently for the from-encoding step (--from-callback) and the to-encoding step (--to-callback), or both at once with --callback. Options include substitute (replacement character), skip, stop (default), and escape-unicode.

参数

-f, --from-code _encoding_

Source encoding.

-t, --to-code _encoding_

Target encoding.

Show default system encoding.

--from-callback _name_

Callback for errors when converting from source encoding to Unicode.

--to-callback _name_

Callback for errors when converting from Unicode to target encoding.

--callback _name_

Set both --from-callback and --to-callback to the same value. Values: substitute, skip, stop, escape-unicode.
