Q: FileStream class>>#writeSourceCodeFrom:* and *TextConverter

Hi,

I'm trying to successfully fileOut and fileIn class and method comments  
with characters codePoint <= 255 (the "european" range of byte size  
characters).

Fileout works but the file looks to have prefix from #writeBOMOn: of  
UTF8TextConverter and file suffix is ".st" or ".cs". On fileIn this fails  
with syntax error :( and Google search did not help. Has anyone experience  
with source code fileOut/fileIn for the "european" character range?

Did a quick shot on FileStream class>>#writeSourceCodeFrom:*, with  
#isAsciiString replaced by #isWideString (followed by ifFalse:ifTrue:),  
filed out again and then fileIn was happy again.

I understand this is perhaps not really sort of bug, but want a bit more  
than just the ascii characters. So what do you Squeakers recommend, how  
should that be done in a Squeak platform compatible way?

TIA.

/Klaus

  What version is it?  Is should be isAsciiString, yes, and The Etoys
image is in that way.

Found the method in 3.10 and checked it against 3.9 (same method), but in  
3.8 the method source code is garbled (decompiler shows it's the same

Klaus:

One of my last contributions to 3.10 was send warnings to Ken about
sometimes this odd thing happen.

But I find hard to reproduce.
