I would like to report a limitation in the macro parsing engine used in dialog text fields. I confirmed this behavior in the "Bookmark Every N-th Page" dialog, but it likely affects all dialogs that rely on the same macro system.
Problem:
It is currently impossible to end a text string with a percent sign (%) that immediately follows a macro value.
Steps to reproduce:
- Open the "Bookmark Every N-th Page" dialog.
- Enter %[page]% in the Bookmark Title Template field where macros are supported.
- The trailing % is ignored by the parser and does not appear in the bookmark output.
I tried several possible escape methods, but none allowed the percent sign to appear:
- %[page]\%
(backslash does not escape it) - %[page]`%
(backquote does not escape it) - %[page]%%
(outputs "5%%" rather than "5%" when the page number is 5, for example, so it's impossible to produce a single percent sign) - %[page]%
(even inserting a Zero‑Width Space U+200B between ] and % does not prevent the parser from swallowing the percent sign)
This issue occurs only when the percent sign is the final character after a macro.
If any additional character is appended (e.g., "%[page]%X" or "%[page]% "), the percent sign appears correctly.
This strongly suggests that the parser incorrectly attempts to treat % as the beginning of another macro and fails to fall back to literal output when % is the final character.
Expected behavior:
After completing a macro such as %[page], the parser should treat subsequent characters literally, including a percent sign. This is a natural use case when users want to display values like "5%".
Hoping that the above information will be of some help to you.
Thank you for your hard work on this great software.
Best regards,
