Directories of the TeX Fonts Metric (tfm)

TeX4ht searches the hypertext fonts in the working directory, and in the following optional directories, in the given order.

The directory named in the command line of tex4ht, identified with the prefix ‘-t’.
The directory identified with the character ‘t’ in the tex4ht.env file.
The directory whose name is fed into tex4ht.c during compilation time, through the program variable TFMDIR.
In the directory holding the executable tex4ht (only for MS Windows).

A given address may start with the character ‘~’ or the character pair ‘~~’. The single character ‘~’ is interpreted to be the directory address of the root, provided in an environment variable named HOME. The character pair ‘~~’ is interpreted to be a directory address provided in an environment variable named TEX4HTTFM. The address stored in the latter environment variable may also start with a single character ‘~’.

The optional environment variable TEX4HTTFM may hold one or more addresses. The addresses must be separated by a character which does not appear in the addresses, and that character must also delimit the content at the start and end points.

The system variable MAXFONTS of tex4ht.c places a limit on the number of fonts allowed in the documents. The default setting doesn’t provide such a limit.

If the program tex4ht.c is compiled with the ‘-DKPATHSEA’ switch on, TeX4ht ignores its own search and delegate it to the kpathsea utility.

A given address may start with the character ‘~’ or the character pair ‘~~’. The single character ‘~’ is interpreted to be the directory address of the root, provided in an environment variable named HOME. The character pair ‘~~’ is interpreted to be a directory address provided in an environment variable named TEX4HTA. The address stored in the latter environment variable may also start with a single character ‘~’.
