Fix two incorrect Unicode mappings in the CCSET_EXTENDED_SPANISH_FRENCH_MISC character set: 1. OPENING SINGLE QUOTE (0x26) was incorrectly mapped to U+00B4 ACUTE ACCENT. Per CTA-608-E Section 6.4.2, it should map to U+2018 LEFT SINGLE QUOTATION MARK to mirror the standard apostrophe (U+2019), which is already correctly mapped in the basic character set. 2. PLAIN SINGLE QUOTE (0x29) was incorrectly mapped to U+2018 LEFT SINGLE QUOTATION MARK. It should map to U+0027 APOSTROPHE, the neutral (vertical) glyph.
