[Tex/LaTex] Monospaced font with U+1D400..U+1D7FF range (for editing)

editorsfontssymbolstexlipseunicode

The goal of this question is to find an appropriate font for the editor in which I input TeX, rather than a font for use in the output. I hope this is sufficiently on-topic for TeX.se.

I recently switched to unicode input for all mathematical operators. Now I'm considering taking it one step further and using the Mathematical Alphanumeric Symbols range to match the font-style of the input to the font-style of the output (upright for functions, italic for variables, script/double-struck/fraktur for the appropriate mathematical concepts).

It's become a bit of a personal project to get my TeX code to resemble the output as much as possible.

The problem so far is that I have no font in which those characters all occupy the same horizontal space, making the code in the editor misaligned and harder to read and edit:

enter image description here

The above screenshot fragment is from Eclipse / TeXlipse, but every Linux editor I tried does the same. The only font on my system that supports that particular unicode range is XITS, so whichever font I choose in the editor, it falls back to XITS for those variables.

Is there a font around which covers as much unicode as possible (but at least the standard mathematical operators and U+1D400..U+1D7FF) and has all of them in the same width? (What's the technical term; monospaced, fixed width?)

Or perhaps there is a way to display the characters with a fixed width, regardless of font? It feels like it would be a fairly mechanical process to take a font such as XITS, center each character in a fixed-width space and output a makeshift font with the characteristic I need. But I have no idea how to do that.

There are very few fonts which cover all languages (let alone mathematics; see threads at typophile and stackoverflow), but Everson Mono seems to do what you want, although it'll cost you 25 euros.

[Tex/LaTex] Unicode in XeTeX with automatic font substitution

This answers tries to complete the previous answer and the comment for a "need to mix-and-match Unicode fonts". The package ucharclasses is meant for this "patchwork".

\usepackage{ucharclasses}
\usepackage{fontspec}

\setDefaultTransitions{\fontspec{Code2000}}{}
\setTransitionsForLatin{\fontspec{Palatino Linotype}}{}
\setTransitionsForGreek{\fontspec{Galatia SIL}}{}

Then xetex will switch the font when the text enters a new Unicode block.

I tried to combine this with Ulrike Fischer's code that checks if a font could be loaded. It seems to work:

\usepackage[Latin,Japanese]{ucharclasses}
\usepackage{fontspec}

\setmainfont{FreeSerif}
\ifnum\the\XeTeXcharglyph"D5=0
  \setTransitionsForLatin{\fontspec{FreeSerif}}{}
\else
  \setTransitionsForLatin{\fontspec{URW Palladio L}}{}
\fi

\setTransitionsForJapanese{\fontspec{VL Gothic}}{}

[Tex/LaTex] Environment with handwritten font with math support

that had the following characteristic proof environment: input \solution[of Jhon] output Solution of Jhon. with the same source document.

I'm not sure what you're asking here. You can use

\def\solution[#1]{Solution #1.}

to do that, but you use the word 'environment', so I think you might want (using LaTeX3)

\usepackage{xparse}
\NewDocumentEnvironment{solution}{o}{\textbf{Solution\IfValueTF{#1}{ #1}{}. }}{}

You can add further formatting commands to this as per the usual definition of an environment.

who had a handwritten fonts such as those packages in The LaTeX Font Catalogue

On each font page, there's a list of 'Style examples'; before each style there is a command which switches to that font. For example, to use the JD font, use \ECFJD. You can add this to the definition of the solution environment above.

As in the answer to question "Handwritten font with math support" I wish there was also support for the math mode.

None of these handwritten fonts has the symbols needed for typesetting mathematics; for mathematics, you're limited to

The maths fonts in the LaTeX Font Catalogue,
OpenType Maths Fonts, which you should load using the unicode-math package, which will require compiling with XeTeX, or
using a normal TrueType or OpenType handwritten font (there are hundreds on the internet), loading it using the fontspec package, and using it as the maths font with the mathspec package, which will also require compiling with XeTeX.
