Except for the most common symbols such as letters, numerals, and basic punctuation, rendering of Unicode mathematical symbols can be inconsistent in size or alignment where fallback fonts do not match, and some readers may not have any font which includes certain uncommon symbols. Spaces within a formula must be directly managed (for example ...
Encodes appearance rather than its semantics. Difficult to process in software. Unable to handle square roots, vertical fractions, and other common formula types. Proper use (italic variables, protected spaces around operators) requires care and is a frequent source of mistakes. "texhtml" templates, such as {} Encourages standardized notation.
The template attempts to use any calligraphic font that may be installed on several operating systems, either as default or as part of an office package. The fonts called are: Lucida Calligraphy, Monotype Corsiva, URW Chancery L, Apple Chancery, and Tex Gyre Chorus. Failing all these, the generic font families cursive and serif are used.
The less-than sign with the equals sign, <=, may be used for an approximation of the less-than-or-equal-to sign, ≤. ASCII does not have a less-than-or-equal-to sign, but Unicode defines it at code point U+2264. In BASIC, Lisp-family languages, and C-family languages (including Java and C++), operator <= means "less than or equal to".
For most symbols, the entry name is the corresponding Unicode symbol. So, for searching the entry of a symbol, it suffices to type or copy the Unicode symbol into the search textbox. Similarly, when possible, the entry name of a symbol is also an anchor, which allows linking easily from another Wikipedia article. When an entry name contains ...
The following table lists many common symbols, together with their name, how they should be read out loud, and the related field of mathematics. Additionally, the subsequent columns contains an informal explanation, a short example, the Unicode location, the name for use in HTML documents, [1] and the LaTeX symbol.
One may set formulae using LaTeX (the <math> tag, described in the next subsection) or, in certain cases, using other means of formatting that render in HTML; both are acceptable and widely used, except for section headings, which should use HTML only, as LaTeX markup might cause uneven spacing in the table of contents, as well as the ...
There is at least one OCR tool that can convert a handwritten formula to Latex and other formats. Mathpix allows 10 snips a month free. I don't know enough to edit the body of the Help page (I've not yet used Mathpix so don't know how good it is, and how compatible with Wikipedia, and don't know what else is out there), but I think there should be a Tools section with this sort of information.
