Fonts with spaces (e.g., "Noto Emoji", "DejaVu Sans") were failing auto-installation because fontSearchTerm() generated search patterns that didn't match font files. Font files use concatenated names without spaces (NotoEmoji-Regular.ttf, DejaVuSans-Bold.ttf). Replace spaces with \s* regex pattern to match files with or without spaces. Closes #13726

When rendering PDF with fonts that have spaces in names (e.g., "Noto Emoji", "DejaVu Sans"), automatic package installation fails:
The
fontSearchTerm()function preserves spaces, but font files concatenate names:NotoEmoji-Regular.ttf,DejaVuSans-Bold.ttf.Fix
Replace spaces with
\s*regex pattern for tlmgr search. Pattern now matches both with and without spaces.Verified with manual testing and unit tests.
