But there are problems with the math: Greek Symbols: are needed in roman (upright) and italic shapes (available as "Mathematical Alphanumeric Symbols" or via font-change) and in some cases (tensor symbols) sans-serif. Spaces: Separate value and unit by a small space: 1 -> 1/2 en -en 2 Fonts: The Unicode block mathematical alphanumeric symbols provides style variants for Latin and Greek letters and digits. It is "to be used for mathematical variables where style variations are important semantically". However, only a few fonts support this Unicode Block. Maybe the --unicode option could switch to use of Unicode Math symbols generally and not only for the spaces. See [tr25]. "Regular text is shown italicized. Variable: length, µ, Speed." While the statement is true and the behaviour right, the example is misleading: Variables should be one-letter symbols. Using full words like length and Speed as variables is not recommended. If full words are used as index (s_in, s_out), they should be set upright (s_\mathrem{in}). See [fonts-for-symbols] and [typefaces] SI units: Units must be set upright (and separated from the value by a space). Whether they use the math- or text font is not mandated (57 \mathrm{km} or or 57 \textrm{km} or 57 \text{km} or \siunit{57}{km}). See [SI-brochure]. Fractions: Would it be possible to have a smaller font size for inline fractions? Arrays: The brackets are too small. You might use the "extendable" brackets provided by unicode block Miscellaneous Technical (which also provides big sum and integral symbols): ⎡1 2⎤ ⎢3 4⎥ ⎣5 6⎦ A more comprehensive test case would be the LyX Math Guide.
