Command line sync fails when brackets are in output file

[Dr-W00]

Running subsync-cmd (V0.17.0) in Windows 11. I have movies that are in the Plex suggested naming convention of \movies\MOVIE NAME (YEAR) {imdb-ID}\MOVIE NAME (YEAR) {imdb-ID}.EXT. When running subsync-cmd I get the error "Invalid output pattern". Replacing brackets with parenthesis it runs fine. Brackets in the sub file or ref file don't cause a problem, just the output file.

Otherwise, it runs like a peach. Slick piece of work.

FWIW - the screen copy below:

M:>subsync-cmd --effort=0.9 sync --sub="M:\Media\Movies\X-Men (2000) {imdb-tt0120903}\X-Men (2000) {imdb-tt0120903}.en.srt" --sub-lang=eng --ref="M:\Media\Movies\X-Men (2000) {imdb-tt0120903}\X-Men (2000) {imdb-tt0120903}.mp4" --ref-lang=eng --ref-stream-by-type=audio --out="M:\Media\Movies\X-Men (2000) {imdb-tt0120903}\X-Men (2000).en.srt" --overwrite
