I get a glyph, but if I try to enlarge the view, it converts to a '?'.
Hence, it appears to be a problem of having the right fonts available.
Perhaps there is some probrem in glyph(?) or font or browsers(?)
I think it is mainly a glyph issue. I checked the Unicode charts
(U3000.pdf, UFF00.pdf, U32-3000.pdf, U32-FF00.pdf), and the sample
glyphs they use for U+301C and U+FF5E are quite similiar.
The following note is made about U+301C:
This character was encoded to match JIS C 6226-1978 1-33 "wave
dash". Subsequent revisions of the JIS standard and industry practice
have settled on JIS 1-33 as being the fullwidth tilde character.
-> 3030 wavy dash
-> FF5E fullwidth tilde
It should be noted that Unicode does try to deal with round-trip
conversion issues. For example, converting euc-jp to unicode and
then convert back to euc-jp. Ideally, you want this to be an
identity transformation, but sometimes there are ambiguities.
With respect to MHonArc, it only goes one way: euc-jp -> unicode
(character entity references). Hence, it does not have to address
There may be a use in having the ability to tell MHonArc how
to map characters, overriding the default tables. Maybe something
like the following:
The first line signifies the character/code set name. Subsequent
lines associate Unicode code points to code points in the specified
This would allow a user to customize MHonArc::CharEnt conversion
tables to resolve an ambiguity according to the preferences of
a particular locale. It seems that visual appearance is the most
important issue, but one would have to be careful since making such
changes could affect other software, like search engines.
Would such a feature be useful?
