Gary Gregory commented on CODEC-159:
------------------------------------
Thoughts from the community? I am worried about b/w compatibility for edge
cases that may rely on > ASCII values.
> BaseNCodec uses UTF-8 rather than US_ASCII for byte conversions
> ---------------------------------------------------------------
>
> Key: CODEC-159
> URL: https://issues.apache.org/jira/browse/CODEC-159
> Project: Commons Codec
> Issue Type: Bug
> Reporter: Sebb
>
> According to RFC 4648 [1], base32 and base64 should use the US-ASCII charset.
> However, the code currently uses UTF-8.
> This should not make a difference when converting from byte[] to String,
> because the bytes will always be US-ASCII.
> However, depending on how the conversion treats characters which are UTF-8
> but not ASCII, it could affect the behaviour when decoding non-ASCII strings.
> Should the code use newStringUsAscii(byte[])/getBytesUsAscii(String)
> throughout?
> Some of the Javadoc will need adjusting if so.
