Special charecteres and transcode
Hi All
I have a probleme the special charactere
so I have a methode that get a string , this string can conteaint some
special caractere like
"ϑ ϒ ϖ – — ‘ ’ ‚ “ ” „ † ‡ • … ‰ ′ ″ ⁄ € ℑ ℘ ℜ ™ ℵ ← ↑ → ↓ ↔ ↵ ⇐ ⇑ ⇒ ⇓ ⇔ ∀
∂ ∃ ∅ ∇ ∈ ∉ ∋ ∏ ∑ − ∗ √ ∝ ∞ ∠ ∧ ∨ ∩ ∪ ∫ ∴ ∼ ≅ ≈ ≠ ≡ ≤ ≥ ⊂ ⊃ ⊄ ⊆ ⊇ ⊕ ⊗ ⊥ ⋅
⌈ ⌉ ⌊ ⌋ 〈 〉 ◊ ♠ ♣ ♥ ♦"
so when I use transcose, somme of this characters changed to ????
thus is My code
I put my string in this variable strMessage
XMLString::transcode("Message",xmlChTempStr,(LENGTH_TEMPORAL_STRING - 1));
DOMElement * chmessage = m_xmlDoc->createElement(xmlChTempStr);
chText->appendChild(chmessage);
XMLString::transcode(strMessage,xmlChTemStr,(LENGTH_TEMPORAL_STRING - 1));
textNode = m_xmlDoc->createTextNode(xmlChTemStr);
chmessage ->appendChild(textNode);
any help plz
best regard

XMLString::transcode() converts between the local code page and UTF-16,
which is Xerces' internal format.
It's not a good idea to depend on the local code page, since it can vary
between systems, and your current local code page may not support all of
the characters you're interested in. That seems to be the case here.
You should either keep all of your data in UTF-16, or use a transcoder
for the actual encoding of your data. If you don't know the encoding of
your data, that's the first problem you need to solve. Once you've done
that, you can create a transcoder for the correct encoding.
There are numerous postings in the archives that will contain more
details that will help you. I suggest you search the archives, do some
research, then post again if you have more questions.

It depends on your operating system and display mechanism.
Windows GUI applications (.Net, MFC, and GDI based) will display full Unicode via UTF-16. Xerces uses wchar_t to hold UTF-16, so the conversion to UTF-16 in Windows' WCHAR_T is a character-by-character copy.
Windows console will only display 8-bit.
Linux/Unix I think has full display via X-Windows and toolkits that use, it if you choose an appropriate font. I don't know about Linux/Unix console, but I think that you can convert to wchar_t and use printf with "%ls" format. Maybe someone else on mailing list can fill in Linux/Unix, that is not my expertise.
You might also look into the ICU library, which has a very large selection of transcoders.

Hi John
Thanks for your response
So If I cannot use Unicode an 8-bit wath I can Used to display all
characters ??
thank you again

If you are transcoding from Unicode an 8-bit code page, not all characters are representable.
