TT,
You are right to raise these issues. I suppose I am now on the Journey to
understand Unicode and make use of it.
here are a few observations;
- MS Windows has fonts to address many Unicode Characters
- There exists a "last resort font" for Unicode
- There are as many as 120,000 Unicode characters, most in different
languages and of reduced value to non speakers of each language.
- Outside of English many languages make use of diacritical characters,
ie marks applied to other characters.
- This facility can also be used to create compound characters, for
example the common "no smoking symbol" circle with a /, can be applied to
other characters
- Tiddler titles can use many of these additional characters including
alternate A-Z, a-z ands 0-9 characters and others
- Tiddler fieldnames are restricted to the single a-z 0-9 character set
and no Unicode Characters permitted.
- I have not tested Unicode characters with the new slugify widgets.
- I continue to learn about Unicode and their application to tiddlywiki.
