[219] DAO_ONLY_UTF8 or similar

I read that 'string' is an UTF8 string while "string" is a WC-string.

In our game, we will only use UTF8. Always.
It would thus be really useful if there was a compiler flag that tells Dao that "string" should be UTF-8 too. Something like compiling with -DDAO_ONLY_UTF8 so that any string is always UTF8.

Or does it make more sense to define a syntax that transforms "string" into 'string', and automatically include this syntax at the beginning of every script? This feels quite hacky though.

[220⇒219] It is possible to configure some settings in the script

You can use @@X(Y), such as @@PATH() @@ECHO() @@LOCALE(), @@ON(), @@OFF(), to change some of the internal settings. So far, only @@PATH() is documented here: http://daovm.net/space/dao/page/dao_quick_guide#6.3 .

Adding @@ON(MBS) in your codes will allow all "string" to be parsed as multi-byte (utf8) strings. For the rest, see this table,

@@ECHO( information_string )	print "information_string" during parsing
@@ON( MBS )	parse all strings as multi-byte (utf8) strings
@@ON( WCS )	parse all strings as wide character strings
@@OFF( MBS )	turn off the @@ON( MBS ) setting
@@OFF( WCS )	turn off the @@ON( WCS ) setting
@@LOCALE( locale )	set the locale of the program to "locale"
@@PATH( + path )	add path to the path list for module searching
@@PATH( - path )	remove path from the path list for module searching

[221⇒220] and in the sourcecode (as a default for all scripts) ?

I see, nice to know there is such a feature. But to enable it with @@ON(MBS), this has to be done in the script, right? How can I enable this feature in my application?

I digged into the code and found out that it can probably be done by the following:

vms = DaoInit();
vms->options |= DAO_EXEC_MBS_ONLY;

Is this the correct way to do it, or is there another (better) way?

[222⇒221] Right

That's the correct way to do it in your application. It is for all scripts, as long as vms is the only DaoVmSpace struct you use to handle the scripts.
