Editing a file and doing a global search and replace is a tool I have used
since PC's were invented. You only do it, or edit characters on a disk or in
an executable file if;

1. You know what you are doing
2. It will save you a lot of time
3. You make a backup first and rigorously test the result
4. You identify what assumptions or exceptions may exist
5. If you have a tool that understands the rules, and does the job use it
first (eg; TiddlerTweakerPlugin)

In the case of TiiddlyWiki source it is quite structured and values can
reside in quite clearly delimited "field"s with the appropriate identifying
values around it.

Yes, if you have CRC's, encryption etc... you may not be able to modify that
part. If you understand what delimits values then you can change things
within those delimiters without harm - if the delimiter is size you must
retain that size.

TiddlyWikis source is very structured with keywords and fully delimited
without special characters.

It is amazing how much you can learn looking "under the hood".
