Created attachment 204862 [details] DOCX Fileopen attached DOCX. Equation interval with brackets shows inverted question marks. Should be: [0;+∞[ Never worked, there was change in 5.4. commit eeadfca73794593b07829b4ffa36c97dff59660c [log] author Takeshi Abe <tabe@fixedpoint.jp> Sat Mar 25 16:27:19 2017 committer Takeshi Abe <tabe@fixedpoint.jp> Thu Mar 30 11:08:39 201 starmath: Hold error nodes as subnodes of SmBracebodyNode https://gerrit.libreoffice.org/c/core/+/196303 to fix that thanks to Pranam.
Still there in december 2025. In fact, I wouldn't consider this as a bug, since the specific formula description language (in LO) doesn't consider left [0 ; "+" ∞[ as a coherent formula. The original formula inside the docx file lacks of coherence also ("left" without "right"). However, the proposed bug could be reconsidered as ENHANCEMENT : while importing math formulas from a docx file, delimiters like [ ( ) ] could be inserted as "[" "(" ")" "]".
