It does work in Integrated Oberon:<br>
<br>
<a href="https://schierlm.github.io/OberonEmulator/emu.html?image=IntegratedOberonDiskImage" rel="noreferrer" target="_blank">https://schierlm.github.io/OberonEmulator/emu.html?image=IntegratedOberonDiskImage</a><br>
<br>
<br>
MODULE Esperanto;<br>
IMPORT Texts, Oberon;<br>
<br>
PROCEDURE Test*;<br>
VAR W: Texts.Writer;<br>
BEGIN Texts.OpenWriter(W);<br>
Texts.WriteString(W, "Eĥoŝanĝo ĉiuĵaŭde");<br>
Texts.WriteLn(W);<br>
Texts.Append(Oberon.Log, W.buf)<br>
END Test;<br>
END Esperanto.<br>
<br>
<br>
If you transfer this file to Oberon using (emulated) PCLink, compile it,<br>
and run it while using a Unicode capable font (e.g. Tahoma) in the Log<br>
viewer, the text appears just fine.<br>
<br>
The characters in memory are still 8 bits wide, using UTF-8 encoding.<br>
The "magic" happens when the string gets converted to a Texts.Text,<br>
which is Unicode aware.<br>
<br>
<br>
