> Key: GUACAMOLE-2176
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-2176
> Project: Guacamole
> Issue Type: Bug
> Components: guacamole-docker, guacamole-server
> Affects Versions: 1.6.0
> Environment: Apache Guacamole 1.6.0
> guacd running in Docker container
> Reporter: pilchu
> Priority: Minor
> Attachments: Księgowość.txt

> *Summary:*
> Polish characters in print job titles are incorrectly encoded in filenames
> generated by guacd's virtual printer (Guacamole 1.6.0)
> *Description:*
> When using Apache Guacamole 1.6.0 with the built-in virtual printer
> (redirected printing via guacd), Polish characters in the print job titles
> are not correctly handled. Instead of proper Polish letters, filenames are
> encoded with unexpected sequences (e.g., {{Zawiadomienie o op_263atach.pdf}}
> instead of {{{}Zawiadomienie o opłatach.pdf{}}}).
> This issue occurs only in the filename/title of the generated PDF, while the
> document content itself correctly displays Polish characters. Ghostscript is
> installed and properly invoked in the container, and the problem is likely
> caused by incorrect character encoding or mapping in guacd when converting
> the print job title to a filename.
> *Steps to reproduce:*
> # Use Apache Guacamole 1.6.0 with the virtual printer feature enabled.
> # Print a document with Polish characters in the document title (e.g.,
> containing ą, ę, ł, ć, etc.).
> # Observe the generated PDF filename in the browser or storage location.
> *Guac logs:*
> guacd[15]: INFO: Print job created
> guacd[15]: INFO: Created PDF filter process PID=54
> guacd[15]: DEBUG: Reading output from filter process...
> guacd[54]: INFO: Running gs
> guacd[15]: DEBUG: Beginning print stream: (Ksi\352gowo\234\346.txt \227
> Notatnik).pdf
> guacd[15]: DEBUG: Sending 484 byte(s) of filtered output.
> guacd[15]: DEBUG: Sending 65 byte(s) of filtered output.
> guacd[15]: DEBUG: Sending 2595 byte(s) of filtered output.
> guacd[15]: DEBUG: End of print stream.
> guacd[15]: DEBUG: Print job completed.
> guacd[15]: INFO: Print job closed
> *Expected behavior:*
> Polish characters should be preserved and correctly displayed in the PDF
> filename.
> *Actual behavior:*
> Polish characters in the filename are replaced with sequences like
> {{{}_263{}}}, resulting in incorrect filenames.
