In my LaTeX document, I have used \mathbb and \mathscr. I would like to use the same fonts in the diagrams I create with Microsoft Visio. But on my Windows machines I cannot find mbboard and mathrsfs fonts as mentioned here.
Where can I find these fonts?
The native fonts are not in a format suitable for use outside of TeX, but an OpenType clone called Latin Modern has a maths font available for download here.
After installing this font file in your operating system, in the usual way, you will find these letters in the Mathematical Alphanumeric Symbols range. The 'blackboard bold' letters (\mathbb) are in the Unicode range U+1D538 through U+1D56B (with some letters in the Letterlike Symbols range U+2102 through U+2149), and the script letters (\mathscr) are in the Unicode range U+1D49C through U+1D4B5 (bold script letters are also available).
These are not available as a separate font; entering these symbols must be done using either the Insert > Symbol feature in Microsoft Visio, or through the Windows Character Map.
