Can't enter the text "XMP" followed by colon

It’s impossible to enter the text “XMP” followed by a colon. When I try to type the text shown in this screenshot:

the forum converts it into “XMP.” (“XMP” followed by a period).  Copy and paste doesn’t work around it.  But you can enter it into a Code box:

XMP:AlreadyApplied

 

In the Lightroom and Camera Raw forums, it’s relatively common to discuss metadata issues, and XMP<colon> is a frequent prefix for important metadata fields.

 

A little experimentation shows that typing “P” followed by colon always results in “P.” What is so offensive about P<colon>???  Did high schoolers code the forum platform?

    @Nancy OShea The Embedded Code feature is more precise than text. It preserves formatting & permits syntax highlighting in scripts.  Also, it’s much easier to copy long lines of code with a single-click on the double box icon.  Personally, I think it’s a great feature. Not sure what you have against it.

    Using Code boxes isn’t relevant to writing about photo metadata in the Lightroom Classic and Camera Raw.  There are thousands of fields in many different sections of metadata (EXIF, IPTC, XMP, Photoshop, etc.), and the different sections often have similarly named fields, e.g. both the EXIF and XMP sections have a field named DateTimeOriginal. So the most common way of unambiguously referencing fields in prose is to use the Exiftool notation, e.g. 

    I have hundreds of posts in the Adobe and Lightroom Queen forums that use this notation, often with a dozen or more uses of the notation in a single post.

     

    For example, here is what I wanted to write in a recent bug report:

    Using a code box to reference the metadata field XMP<colon>AlreadyApplied would be needlessly verbose and disruptive to easy reading of the prose -- its referring to a field name, not to a code fragment or script.

    I suppose P colon could be interpreted as an ASCII obscenity. 

    Think long & hard about it. 😉

    XMP is used in ExtendScript and Javascript

    @kglad, here are screen recordings of the misbehavior on:

     

    Mac OS 26.2, Safari

    ASUS mini PC, Windows 11, Edge

    Windows 11 guest on Parallels Mac OS 26.2 host, Edge

     

    Typing P<colon> must be some special permission granted to Community Experts (I’m not being facetious).
