- Download the page which contains diacritics eg: http://geoiptool.com/en/?IP=192.42.43.22
...
- contains
...
- Neuchatel
...
- with
...
- 'a
...
- ' as
...
- a
...
- diacritic.
...
- From a UNIX machine get the dump of the page using command line tool 'xxd' and grep the word so that you get hex dump of the alphabet required eg:
Code Block xxd index.html?IP=192.42.43.22
...
| grep Neuch
...
- The

- output
...
- would
...
- be
