I'm in the process of making my PHP site Unicode-aware. I'm wondering if anyone has experience with the mbstring.func_overload setting, which replaces the normal string functions (e.g. strlen) with their multi-byte equivalents (mb_strlen).

I'm new to Windows programming and after reading the Petzold book I wonder: is it still good practice to use the TCHAR type and the _T() function to declare strings or if I should just use the wchar_t and L"" strings in new code? I will target only Windows 2000 and up and my code will be i18n from the start up. ...
In XEmacs this is done by the calling the function char-to-ucs on a character. GNU Emacs does not seem to have this function. In GNU Emacs, characters seem to be ordinary integers. Running C-x = on a latin character reveals that the Emacs codepoint is different from the Unicode codepoint for the corresponding character. How do I find...
I'm matching identifiers, but now I have a problem: my identifiers are allowed to contain unicode characters. Therefore the old way to do things is not enough: t_IDENTIFIER = r"[A-Za-z](\\.|[A-Za-z_0-9])*" In my markup language parser I match unicode characters by allowing all the characters except those I explicitly use, because my m...
What's the simplest way to convert a Unicode codepoint into a UTF-8 byte sequence in C? The only way that springs to mind is using iconv to map from the UTF-32LE codepage to UTF-8, but that seems like overkill. ...
My client has an old MS SQL 2000 database that uses varchar(50) fields to store names. He tried to use this database to capture some data (via a web form). Some of the form-fillers are from other countries, and the varchar fields went nutty when some of these folks entered their names. Is it possible to recover the data somehow? Maybe by...

I have a simple Google App Engine app, that I wrote using ordinary strings. I realize I want to make it handle unicode. Are there any gotchas with this? I'm thinking of all the strings that I currently already have in the live database. (From real users who I don't want to upset.) ...

I'm using Server.HtmlEncode on a utf-8 string in asp-classic, which works fine until there are some accents in the string e.g. Rüstü Recber, which appears as Rüstü Recber (Rüstü Recber in the source). I've tried setting the Response.Charset property to utf-8 but this doesn't make any difference. ...
