My database server character set is latin5. Accented characters in the result set fools “show results in text” alignment, to my understanding, as much as the utf-8 counterpart bytes for the accented character. Without accented characters in the result set, alignment is still correct. Verified on 6.03 and 6.04.
Please first check the font settings in 'preferences'. Is a non-propotional font (like Courier/Courier New) used everywhere.
Also please help with a small test case! Create a small table with those characters, export/dump , zip and attach here (So that we can “SELECT * FROM …” and reproduce!).
