There is no actual issue with anchors containing : in Info, only when they are referred to. Even in references, if the names are 'quoted', which is the default with texi2any and the info reader supports the quotes there is no issue. I do not think that it is the way forward to add warnings for such names. The way forward would be to have the Emacs Info reader modified to read the quoted nodes such that all the warnings can be off in the default case. In the "‘@node’ Line Requirements" node, this is explicit: • Unfortunately, you cannot reliably use periods, commas, or colons within a node name; these can confuse some Info readers. ‘texi2any’ quotes problematic node names and labels by default, but some Info readers do not recognize this syntax. Node name and label quoting causes ‘DEL’ characters (‘CTRL-?’, character number 127, often rendered as ‘^?’) to appear around the name. To remove node names and labels quoting, you can set the customization variable ‘INFO_SPECIAL_CHARS_QUOTE’ to ‘0’ (*note Other Customization Variables::). ‘texi2any’ warns about such problematic usage in node names, menu items, and cross-references. If you don't want to see the warnings, you can set the customization variable ‘INFO_SPECIAL_CHARS_WARNING’ to ‘0’ (*note Other Customization Variables::). -- Pat
