@Coises said: Have you ever noticed arbitrary junk character replacements with any other regular expression / replacement pairs, or only with this particular one? I haven’t actually tried any others with Search++, so far. The vast majority of my regex operations are accomplished via PythonScript, and I only very infrequently need to perform a standalone regex. But I’ll keep Search++ in mind if/when another one becomes necessary.

Since it’s essentially working at this point, I’ve renamed the Topic to “BETA” @mpheath , I have updated the README at https://github.com/pryrt/NppPlugin-HiddenLexers to enumerate available options I think I’ll be patient, and give the beta test a while longer, so won’t try to rush to release it before N++ v8.9.8’s PluginsAdmin list is finalized.
