Speed of texexec with Unicode TrueType Font

Speed of texexec with Unicode TrueType Font

[Bryant Eastham]

[-- Attachment #1.1.1: Type: text/plain, Size: 1067 bytes --]

All-

Apologies if the question should go to another list - let me know if so.

I am using texexec with MSPMincho on a Japanese utf-8 document. I followed the instructions and it appears to work well.

Texexec runs several passes, and on each pass spends a *long* time integrating each font "page". I get many lines saying:

{<path to enc>/MSPMinchoXX.enc}<<path to tt>/MSPMincho.ttf>

The time taken in this process is many times that of the rest of the conversion. The resulting PDF font properties lists "MS-PMincho (Embedded Subset), Type: TrueType, Encoding: Built-in" 75 times. I imagine that I am glad that the whole font is not included (for file size). However, during development it is painful to wait.

Is there a way to optimize the process?

Thanks,
-Bryant

The pdftex list would have been better, but I think I can answer
anyway.

Large font support in pdftex is suboptimal: for each encoding block
of 256 characters, it has to reload and re-subset the complete ttf font.

It is unlikely this situation will ever improve, and the best option is
to switch to using one of the two new engines: xetex or luatex. This
will need different font commands from the ones you used for pdftex,
though.


Best wishes,
Taco

Can you provide a example.

Have you considered to use MkIV?

Wolfgang-

I can provide an example, but based on Taco's response it is unlikely to be of benefit.

I have in the past tried more recent releases. I was not able to navigate the documentation and bugs to get something working.

As this is merely an optimization issue, I can deal with the performance for now and (once things are all working) evaluate MkIV again in the future.

Thanks,
-Bryant
