I have a text file in UTF-8 containing somewhere a Unicode character that is not present in CP1250*. I want to save the file as CP1250 but both Gedit and Leafpad fail to do so. I do not know which character is actually causing the problem: there is no way to use Ctrl+F to find “characters present in this file which do not exist in cp1250”. The document is long. How can I find the offending character? I know that I could always delete half of the text and proceed with the half that still cannot be saved, but that seems a bit cumbersome. Is there a better way?
* Perhaps, for example, the the file contains ɸ (U+0278), a character which does not exist in CP1250.
