Dear José, 

Cool, thank you really very much for your quick answer! Deleting 
~/.geiser_history.guile fixed the problem. Nonetheless you’ll find the 
requested information below, maybe it will be helpfull for your work 
some day.

Guile 2.0.5, as shipped by Ubuntu. 

Settings in .emacs-custom: 

 '(geiser-active-implementations (quote (guile))) 
 '(geiser-guile-load-init-file-p t) 
 '(geiser-mode-smart-tab-p nil) 
 '(geiser-repl-use-other-window nil) 

The error above usually makes the offending characters clickable and one

The characters are not clickable unfortunately. They seem to be 
escape-characters; but honestly speaking I do not understand what they 
are. "C-u C-x =" yields: 

Char: /303 (4194243, #o17777703, #x3fffc3, raw-byte) point=373 of 848 
(44%) column=34 

Char: /234 (4194204, #o17777634, #x3fff9c) point=375 of 848 (44%) column=39 

Does this happen in fresh new REPLs without any ouput, or only when

It happened in both cases. 

Does moving ~/.geiser_history.guile away fix the problem? (that's the
