Converts between different character encodings. On UNIX, this uses the
iconv library, on Windows the Windows API.
PConverter = ptr TConverter
-
can convert between two character sets
EInvalidEncoding = object of EInvalidValue
-
exception that is raised for encoding errors
proc getCurrentEncoding(): string {.raises: [], tags: [].}-
retrieves the current encoding. On Unix, always "UTF-8" is returned.
proc open(destEncoding = "UTF-8"; srcEncoding = "CP1252"): PConverter {.
raises: [EInvalidEncoding], tags: [].}-
opens a converter that can convert from srcEncoding to destEncoding. Raises EIO if it cannot fullfill the request.
proc close(c: PConverter) {.raises: [], tags: [].}-
frees the resources the converter c holds.
proc convert(c: PConverter; s: string): string {.raises: [EOS], tags: [].}-
proc convert(s: string; destEncoding = "UTF-8"; srcEncoding = "CP1252"): string {.
raises: [EInvalidEncoding, EOS], 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.
