Import a range of glyphs from ttf outline font into the current font as symbols, starting from a specific character position. Note: pcb-rnd font symbols are not unicode code poitns, but consists of a single, 8 bit ASCII code page, thus values above 255 are invalid as destination symbol code.

The srcglyph argumnet is a single character description or a pair of character descriptions separated with two dots (".."). In the former case the import is a single glyph, in the latter case the import is the whole range between the two characters, inclusive (one or more glyphs).

The dstchars argumnet is always a single character description, addressing within the 0..255 range of the pcb-rnd font. This argment determines the first destination symbol that is going to be overwritten. If srcglyph specifies multiple characters, dstchars is internally stepped after each glyp import, up to 255, where the import stops.

A character description addresses a code point on the input or a character code on the output, using one fo the following syntax variants:

- 'A' is converted to 65 (as a single charatcer using the 8 bit ASCII table)
- is converted as decimal number 10
- is converted as hexadecimal number, to 16
- U+10 is converted as hexadecimal number, to 16
- anything else is taken as a single character and is converted as it was wrapped in ''

The 4th argument is either polygon or line. When it is polygon, the glyph is imported as a polygon (with or without holes). When it is line, all contours of the glyph is imported as a series of lines. When not specified, it defaults to polygon.

Finally, scale and offset specifies the transformation during the import. Each argument is either a single number or a pair of numbers separated with comma or semicolon or / or * or x, and specify the x and y components of the transformation. When only the x component is specified, y is assumed to be the same (this is useful for scale).
