Converts between different character encodings. On UNIX, this uses the iconv library, on Windows the Windows API.

    EncodingError = object of ValueError

  exception that is raised for encoding errors Source Edit

# Procs

    proc nameToCodePage(name: string): CodePage {...}{.raises: [ValueError], tags: [].}

    proc codePageToName(c: CodePage): string {...}{.raises: [], tags: [].}

    proc getCurrentEncoding(uiApp = false): string {...}{.raises: [], tags: [].}

  retrieves the current encoding. On Unix, always "UTF-8" is returned. The `uiApp` parameter is Windows specific. If true, the UI's code-page is returned, if false, the Console's code-page is returned. Source Edit

    proc open(destEncoding = "UTF-8"; srcEncoding = "CP1252"): EncodingConverter {...}{.
        raises: [ValueError, EncodingError], tags: [].}

  opens a converter that can convert from `srcEncoding` to `destEncoding`. Raises `IOError` if it cannot fulfill the request. Source Edit

    proc close(c: EncodingConverter) {...}{.raises: [], tags: [].}

  frees the resources the converter `c` holds. Source Edit

    proc convert(c: EncodingConverter; s: string): string {...}{.
        raises: [EncodingError, OSError], tags: [].}

  converts `s` to `destEncoding` that was given to the converter `c`. It assumed that `s` is in `srcEncoding`. utf-16BE, utf-32 conversions not supported on windows Source Edit

    proc convert(s: string; destEncoding = "UTF-8"; srcEncoding = "CP1252"): string {...}{.
        raises: [ValueError, EncodingError, EncodingError, OSError], tags: [].}

  converts `s` to `destEncoding`. It assumed that `s` is in `srcEncoding`. This opens a converter, uses it and closes it again and is thus more convienent but also likely less efficient than re-using a converter. utf-16BE, utf-32 conversions not supported on windows Source Edit
