Hi, Commit 3ed1de0ddccb42bae4151c7225d3fddeab04ff43 should better be reverted, IMO. The ISO organization or their *standards* can be renamed to whatever names; what matters here is what the *encoding* is commonly referred to. The *encoding* names are standardized by IANA: https://www.iana.org/assignments/character-sets/character-sets.xhtml The first ISO 8859 encoding there has the name ISO-8859-1 or ISO_8859-1 and the first among these is the preferred MIME name. So, please, in encoding names: * revert the ISO -> ISO/IEC change, * change the space after ISO to a dash/hyphen-minus. Likewise (partially) for commit d5e5db91ece5955b21ae1aedc03ba1d56d3cf423. Bruno
