bug report: pylupdate corrupts ampersand symbols

Thu Jan 27 16:12:59 GMT 2022

Sure.

1. Take form.ui (which I made in Qt Creator), which has a red label (which
Qt Creator produces by using HTML formatting).
2. Run `pyuic5 -x form.ui -o form.py` to create form.py.
3. Run `pylupdate5 main.pro` to create ja_JP.ts.
4. Open ja_JP.ts in Qt Linguist, and provide a translation of the source
text "<html><head/><body>Colored
Label</body></html>" to "<html><head/><body>Translated Colored Label</body></html>". Save
the ja_JP.ts file in Qt Linguist.
5. Run `pylupdate5 main.pro` to update ja_JP.ts.
6. Open ja_JP.ts and you will see the ampersand symbols.
