@elextr I mentioned the file browser plugin as the most probable cause but it can be anywhere in geany because utils_get_utf8_from_locale() is used everywhere to convert locale to UTF-8 and this function unfortunately doesn't guarantee the result is always UTF-8.
But of course even though I saw this message coming from Geany it doesn't mean it cannot originate in Scintilla in your case. --- Reply to this email directly or view it on GitHub: https://github.com/geany/geany/issues/875#issuecomment-176295661
