Created attachment 59668 [details] file with 1 character : é with encoding ISO-8859-15 Version: 4.0 (using KDE 4.6.2) OS: Linux kate is configured utf8 i open an ISO-8859-15 file with only one character : é the system became totally slow with 100% cpu eat the file is never opened Reproducible: Always Steps to Reproduce: open kwrite or kate (encoding by default is utf-8) set encoding to ISO-8859-15 write the character é save set encoding to UTF-8 ==> 100% cpu ! kill kwrite or kate open kwrite or kate ( encoding is by default utf-8 ) open the file => 100% cpu Actual Results: file is never opened and the system hang Expected Results: file is opened

Git commit 5ce06dacda2f57e03c5d513eba75fadda63505ca by Jan Paul Batrina. Committed on 02/08/2021 at 11:44. Pushed by cullmann into branch 'master'. Do not show encoding error when file only contains BOM failedToConvertOnce shouldn't be set to true when the BOM was processed. After this commit, opening files with the following hex content should open in the corresponding encodings: E9 - Latin-1/ISO-8859-15 EF BB BF - UTF-8 EF BB BF E9 FF - Latin-1/ISO-8859-15 Then forcing the Latin-1 files above to be opened as UTF-8 should show the "invalid encoding" error message properly.
