Re: [Lazarus] Form resize to standard size in IDE.
I (and others co-workers) have experienced the same behavior on Linux mint cinnamon 17.3 when Lazarus is built using gtk2 (using Lazarus 1.4, 1.6, fixes and trunk). This strange behavior disappeared when Lazarus is built with QT. The cinnamon looking glass can provide some debug information about this. I'll try reproduce this tomorrow, to collect the cinnamon debug info.

As Mattias said, the fact that the source unit is UTF-8 encoded.
Defined by a BOM marker, or -Fcutf8 or {$codepage utf8}. If the source
unit is UTF-8 encoded, the literal string constant can't (and
shouldn't) be in any other encoding.
I would say the same if the source unit was stored in UTF-16
encoding. Then string literals would be treated as UTF-16.

Well, the code in tscannerfile.readtoken() only does the conversion to
UTF-16 if the source codepage is UTF-8, otherwise it only converts to
UTF-16 if the string is already an UTF-16 string.
So probably not broken as it seems rather on purpose; if at all it's
wrong...

Never use a GUI to understand dataset events. Because what you get is a mix of how TDataset behaves and how the DB aware controls behave. The DB aware controls do the most strange things imaginable in order to accomodate whatever their designer thought necessary. TDataset just reacts on the commands that the controls give. So, if you want to understand how TDataset events work, you should only use a command-line program, and issue a command (open, next, edit etc), and see how the TDataset reacts.

And if a ISO/Ansi codepage is given? Things would probably fail.
The point is: FPC is consistent in this regard: also sources with a
given iso/ansi codepage are handled the same way. If there is a string
literal with non-ascii chars, it is converted to UTF-16 using the
codepage of the source. Very simple, very logical. It is a matter of
preference if UTF-8, -16, -32 are chosen at this point, but FPC uses
UTF-16. If it uses UTF-8, the problem would occur the other way around.
If no codepage is given (by directive, command line, BOM), string
literals are handled byte-wise as raw strings.

It is logical only in a limited view.

Small correction: FPC only does this conversion if the codepage is UTF-8,
no other.

As Mattias said, the fact that the source unit is UTF-8 encoded.
Defined by a BOM marker, or -Fcutf8 or {$codepage utf8}. If the source
unit is UTF-8 encoded, the literal string constant can't (and
shouldn't) be in any other encoding.
I would say the same if the source unit was stored in UTF-16
encoding. Then string literals would be treated as UTF-16.
It's perfectly logical to me.

Graeme

Yes. Which is good imo. The compiler should call the unicode writeln in
this case and this requires a widestringmanager (where I agree, its name
is chosen wrong, it should be named unicodestringmanager) anyways. If
the string were encoded UTF-8 and the ansistring writeln is called, your
example would work only on a system with an utf-8 console. But you can
achieve the same (broken output) by just leaving away the codepage
directive then. It will not work on non utf-8 consoles either.

Yes, but sometimes the string encoding is not obvious:
{$codepage utf8}
const s = 'äöüالعَرَبِيَّة';
begin
writeln(s); // needs widestringmanager
end.
